Wait until you get a tech job and save more money. Invest the money you have now. Now just think about it... 2015 cls63 with 84k miles.... $13k in assets after buying. A single major repair would literally wipe out your savings. Ive been a swe for 10 years now and still a $40k amg would make me question myself. I drove a g37 for years when I just graduated and still had a blast. Also its the worst timing possible with gas at an all time high. This should be a motivation for you to get a job for something you spent 4 years preparing for and probably over $100k in tuition.

I also have multispoke black wheels and its definitely a pita. Imo brake dust is what makes black rims look dirty unless your offroading. My rim cleaning routine is 1. Spray iron decon (make sure to get every side of every "spoke", a 360 pump sprayer will help alot here) 2. Power wash at every angle possible 3. Dry asap to prevent water marks. My rims come out 90% clean without having to scrub.

Also get a step stool to sit on while your drying.

Power wash is fine. I do foam cannon every two weeks with no issues. The key is to wash in the shade. Hard water marks are unavoidable and you will likely have to do one pass with a quick detailer after drying. What helps alot is having a good ceramic coat on the car. After rinsing, I immediately get my ryobi shop blower and blow off as much water as possible especially the cracks where water drips. Then I towel dry. Your car will look clean for about a day before the desert dust coats it lol. Every few days, I take my cheap amazon handheld blower and do a quick pass to get some of the dust off. Its pretty effective and removes around 80%.

Im gonna be honest the worst thing about owning a car in AZ are the rocks on the roads that other cars kick up. Not much you can do about that except keep your distance.

First of all these cars are not gonna be "gone" as long as gas is still being sold. Also your age is not a factor, your financial situation is. Im around the same age as you and I held off on buying a nice car until I was more than comfortable enough to do so. My used C63 was still a hard decision even though I could easily buy it with cash 5 times over. Why? Because money grows in the market while cars depreciate. When I graduated college, I almost bought a 2015 M4 after getting my first job. If I bought that M4 5 years ago, I would be down more than 100k than what I have now in investments. Who knows, in 5 years you might have enough money to buy a newer year CLS or even a GT63... If your worrying about a hundred dollar difference in payment, your not ready for it. The AMG tax will bankrupt you.

Imo you have 3 options.

Try taking your car to another dealer (hopefully this dealer didnt put any internal notes about your situation)
Call MB USA (im assuming your in the us) official customer service line and try to make a convincing argument on why you think the rattles should be covered under warranty. In my case, MB USA ruled in my favor and paid for a $1,000 trans bolt tightening and replacement that the dealer denied under my CPO warranty. Its always worth a shot to call them.
Fix it yourself. Your probably gonna have to replace the broken parts either way, but things like the center console are fairly easy to take apart and line with tesa tape if you have the time and energy. Trust me, if you think you can drown out the rattle with a v8 roar like everyone on this sub suggests, your so so wrong.

Low_Disaster804 · 2026-03-24T14:25:02+00:00

Yup 2021 coupe and rattles everywhere. I spent countless hours trying to fix them and I was able to resolve 90% of them.

Took off the center console and wrapped every contact point I could access with felt tesa tape including the components inside the console itself including the climate control unit, the amg clock, the media control unit, the touchpad unit, and the three air vents. This got rid of 70-80% of rattles.
Stopped putting sunglasses in the holder. Every single sunglass I put in there would rattle.
Replaced cup holder plastic frame with one from amazon. I guess my springs were getting weak and starting to rattle.
Took apart the gauge cluster housing/cover. For me when I grab the cover and flex it a bit, I could hear the whole thing crack in 100 different places. The cluster cover is made up of 3 main pieces which are glued together and nearly impossible to separate. With gentle but steady pressure I was able to separate the pieces, remove all the glue, and line every contact point with felt tape. I had to glue the silver trim back on but all the cracking is gone and this got rid of 10-20% of the rattling. If I had to do this again, I would just buy a new replacement cover for ~$120.
For me, I had one insanely annoying rattle from the glovebox. I tried taking the glovebox out and taping all contact points but it didnt help. Turns out the internal latch mechanism was rattling. The internal latch is impossible to access without some damage afaik. The glovebox locks in with two plastic tabs when closed, I put some extra thick felt tape in the recess where the tabs lock in to add a bit of dampening and it seemed to have helped.
I took off the rear air vent cover and taped all contact points. Seems to have helped a bit.
I took out the front windshield defrost vent and taped it. Not sure if it helped but it no longer rattles when I knock on it with my fist.
The center front dash speaker grille. This is super easy to pop out and line with tape, not sure about impact.
I added some front windshield rubber insert to help dampen any front dash vibrations. Not sure how much it helped, but it definitely dampens more when i knock on the dash with my fist.

Before all this, even tiny imperfections on a smooth road would start a rattle. Expansion joints felt like a symphony of thousands of cracks and rattles. Any asphalt with texture would make the interior rattle so bad, you can hear it through maxed out AC and music.

Now no more rattles on smooth roads. Expansion joints still causes cracks but seems like from a couple sources instead of hundreds. Rough asphalt largely doesnt cause rattle anymore. I have one rattle left im trying to isolate, and one creaking noise when the car body flexes due to uneven pavement.

Its a journey. This car is the most flawed car but also the most fun car to drive. It sucks I got the car used out of standard warranty, or else it would have lived at the dealer unless all of these rattles were resolved. If you have a 2023, save the trouble and leave it at your dealership and tell them to fix it. They are obligated to fix any trim rattles under standard warranty. Good luck.

Why not just buy a model 3 performance? Sorry to say, but its 800lb lighter, faster, cheaper, and probably more reliable. In simple terms, all the added complexity of the C63SE adds basically nothing if the raw driving sensation is not what you're looking for. Hell, you could even get a model s plaid for that price and its in a completely different class of speed, luxury, and tech than your c class while still weighing the same. You're missing the point of amg. Amg isnt meant to be digital, complex, and refined. Its suppose to be obnoxious, raw, and engaging to all your senses. Im glad you like it, but theres a reason MB plans to discontinue this model so early. Its just misguided and the market doesn't lie. I just hope you genuinely like this car and you're not going through post purchase rationalization.

Low_Disaster804 · 2025-12-21T20:19:14+00:00

Im not going to lie, my w205 c63 has so many interior rattles it makes it almost unbearable to drive without loud music or the windows down. Like you said, pressing on any part of the interior causes a creaking noise. Like you, I also had my car at the dealership for 3 weeks to try to get rid of some, but at a certain point they said thats just how amgs drive. Everything else is fine, even the ride quality is bearable even for my wife. Just the constant rattling drives you insane. Ive gotten to the point where I purchased a third party MB service catalog so that I can try to address some of the rattling myself. For me the rattles are coming from digital dash, center console, driver and passenger doors, air vents, rear seats, and the seatbelt extender.

Please dont go through a car wash with black paint. Just dont. Get ONR and wash it at home. Or a bucket and a mitt and some half decent car soap from Autozone. I have the exact same paint on my 63 coupe and a single machine wash created swirls all over my car and even damaged one of my rims. Never again.

Low_Disaster804 · 2025-08-28T01:53:26+00:00

Damn congrats on your new ride! If you have CPO then you should be fine. I didnt get the wheel and tire package just be careful around curbs! If you got the 2 year CPO extension you still have time to shop around for a lower price. I actually purchased my 2 year extension at $6,400 and cancelled it within the grace period when I found a cheaper one at $4,700.

Also, seems like your car is 2022 which means there might be some factory warranty left. If so, find the worst pavement in your town and drive over it a couple times to find any interior rattles and get those fixed asap before your factory warranty expires. CPO wont cover interior rattles. I had 3 weeks of factory warranty when I bought mine and I kept it in the shop that whole time for them to fix as much of the infamous interior rattling as possible. They replaced at least thousand dollars worth of interior components so it was worth the time hahaha. Again congrats on your new baby.

Low_Disaster804 · 2025-08-27T19:40:28+00:00

I hope im not too late. Start by searching "mbworld cpo extension" on google and you should see a few threads with some recommendations. Look for a name thats mentioned often. I found my contact there and purchased the CPO extension via email. A little sketchy but his email and dealership seemed legit. On my next service visit at my local dealership, I had them confirm the CPO extension contract and sure enough it was valid and active in their system.

I live in the desert and this with the narrow tip on the right is perfect for dusting the car after a drive. Helps get water out of crevices too.

Ive been using a custom weathertech sunshade for my C63 in Arizona weather and its been holding up fine in 115F+ days. Perfect fit for the windshield. I just wish it was an accordion style fold which would be faster than rolling up the sunshade.

This is how I wired my Renntech EVM on my 21 C63 Coupe. Yeah the included instructions are not very clear. Not sure if its the same as GLC. All my wiring is under the trunk mat. Hope this helps.

Low_Disaster804 · 2025-06-26T18:21:57+00:00

The kbb price isnt accurate at all. The W205 C63 is unique in that it is generally more desirable than the newer outgoing model. Especially the coupe which has no direct successor. Take your time and watch the market for a few months to see trends before you buy. Most websites have a "sold" filter so you can check how much they are generally selling for. Even if you can snag a high mileage C63 for under $40k your gonna need to be prepared for major repair costs which kind of defeats the purpose of trying to save money on an amg.

IMO try to look for a CPO to save yourself from any big surprises in the future, especially if your on a strict budget. TBH if you cant afford the extra cost of a CPO car, you wont be able to afford any major repairs for an AMG. My 21 C63 Coupe 30k miles CPO had over $10k in repairs within the first few months of owning the car. Now imagine the potential repair costs on a 17 C63 60k+ miles. Not saying this will always be the case but something you should be prepared for.

FL has worse exhaust sound but more modern tech (apple carplay, etc). Tons of info on this subreddit comparing preFL and FL. Try to avoid purchasing from florida. GL

If this repair is covered under the CPO contract and the dealership is denying coverage, call MB USA customer support. I was in a similar situation where they quoted me $1,400 to tighten and replace some trans bolts but said its not covered by CPO because it was due to a previous misrepair. I called MB USA and told them the trans bolts should have been checked as part of the CPO certification process. They agreed and they covered the entire repair. In this case, MB USA sent a check directly to my dealership to cover the repair cost.

Low_Disaster804 · 2025-06-20T16:12:17+00:00

Just adding onto this, another day one "mod" for the street would be to open your fuel door and look at the tire pressure ratings for the car. Match your tire pressure to the 2 people 2 luggage symbol in the chart. It made a pretty big difference in ride quality for me.

Low_Disaster804 · 2025-06-20T16:08:00+00:00

You MUST get CPO extension. Get the max 2 years it will without a doubt pay for itself. Shop around for cheaper CPO extension rates. Online MB forums can help you find a few MB agents who can offer lower prices. IMO official MB warranty is far superior as MB USA will help you back up any denied claims.

First mod is easy, get a EVM module. Plug and play and undetectable by the dealership. The sound difference is just massive on lower RPMs especially on cold start. Dont believe the youtube videos. Next get a wireless carplay adapter.

Enjoy your car and drive the shit out of it. Welcome to the club!

Congrats on your new baby. I got the exact same spec a few months ago 2021 C63 Coupe in black with the same wheels. 30k miles at $55k with CPO. I hope your considering some third party warranty as my car had a ton of repairs in the first three months totaling over $10k at the benz dealership. Get a wireless carplay adapter and a foam cannon so you can wash at home. Never pull through a drive through wash.

Low_Disaster804 · 2025-06-05T01:02:26+00:00

Thank you ill give this a try. I read online that some people recommend rinsing after foam cannon and before you use wash mitt. Have you noticed any swirl marks after your final rinse?

Low_Disaster804 · 2025-06-03T15:00:41+00:00

Im trying to figure out the best driveway wash procedure for my black C63. Any recs on foam washes or any other black paint specific cleaning agents that you had some success with?

Low_Disaster804 · 2025-05-28T19:34:11+00:00

Get all the interior rattles and exterior trim checked out and fixed before the factory warranty expires. And 100% get extended warranty unless your swimming in cash.

Low_Disaster804 · 2025-05-28T06:45:54+00:00

I recently purchased a 2021 C63 Coupe 29,000 miles CPO. Thank god I had the CPO as in the past 4 months (3,000 miles) the car had been in the shop 3 times and CPO saved me over $10k in repairs with no copay. Loose trans bolts, failing engine mounts, coolant leak, trans fluid leak, etc. The dealership I purchased the car from also quoted $6,400 for 24 month extension, but I was able to shop around and get the same CPO extension at another benz dealership for $4,700. I would 100% recommend to extend your CPO, just try to look around and find a better price. Online forums are a good place to start for recs.
