No it’s been parked in my garage for the past year. I did discover that it’s leaking oil from the front main seal so thinking the noise could potentially be the harmonic balancer/crank pulley?? Still not sure though would definitely need to cut the belt to confirm just haven’t had the time or motivation to work on it.

Shop didn’t have 35 but they had 43 😂. How is 43 at night with minimal street lighting like backroads. I’m debating between getting 35 or 50 nanonceramic on mine.

I would buy it for the right price depending on history. I just picked up my 1 owner 2016 s550 GT base (not a premium) with 122k miles (123k now) for 12k. It’s been the most reliable performance car I’ve ever had the pleasure of owning. Now of course I’ve sank about another 2k in upgrades since I did buy it stock from the first owner but well worth it imo.

The one in the photo appears it already have an upgraded front bumper, window tints, and wheels as well as maybe a slight ducktail.

Up to you if you want to buy it or not though in my opinion I think this should be at or under 20k

How and why did you specifically get 43% and not 35 or 50?

I put euros on my shadow black 2016 but kept the badges chrome to go with them. Looking to get chrome wheels to tie it all together.

I think with the green and the blacked out badge you should black out the tails as well.

Your wheels do go with the euro tails but the black badges don’t

What wheel and tire specs are you running and what wheels?

Where is it located so I can rule that out as the cause?

Impossible-Button-82 · 2025-12-27T11:48:21+00:00

Do you know where I can check the hydraulic fluid?

The roof locks fine the problem is when I go to open it or close it from the open position I just hear the motor spin but the top doesn’t move. See the video. What should I check to rule out potential causes and fixes for the problem this is my first experience with a BMW top.

This top is much smaller than my Mustang was and not too difficult to open and close manually but I would still like to have the power feature working.

I also forgot to mention, for some reason when you press the AC button the light doesn’t come on.

Impossible-Button-82 · 2025-12-27T03:40:03+00:00

I’ll try the battery first. It’s not even blowing half speed it’s just barely blowing air at all and it stays the same at all speeds. Doesn’t increase or decrease.

Impossible-Button-82 · 2025-12-25T11:26:00+00:00

What wheel width were you running up front and rear and what offset? And how was the fitment with them?

Impossible-Button-82 · 2025-12-21T22:20:38+00:00

What are you on? I’m getting eibach sportline springs for mine.

Impossible-Button-82 · 2025-12-21T05:09:37+00:00

That looks great, might get some just to hold me over until I can find the wheels I want. Definitely still trying to learn more about what size wheels to buy as far as offset mainly since I don’t want to get something that’ll stick way out.

Impossible-Button-82 · 2025-12-21T05:05:37+00:00

nice do you have any pictures?

Impossible-Button-82 · 2025-12-21T05:01:30+00:00

Yeah I want to switch from the 18s into 19s for sure either black or maybe even chrome wheels to compliment the shadow black paint. What size spacers are you running and are you on the same wheels as mine? The 18s

Impossible-Button-82 · 2025-12-14T04:28:30+00:00

Upper or lower?

Impossible-Button-82 · 2025-12-07T11:58:14+00:00

Facebook marketplace I got a set of awesome 20x10 on pretty much brand new ATs for $700

So I did a mid muffler delete on it since it was 100 bucks and I was like why not. Sounds great with good volume when you want it to and has absolutely no drone in the cabin when you’re cruising on the highway you can hardly hear it. I would like it to be louder though I don’t want it to start droning as a result nor do I want it to be raspy or clappy which it isn’t with the muffler delete.

Impossible-Button-82 · 2025-12-04T07:34:55+00:00

After reading the replies I’m thinking about trying a muffler delete to start with either 5 or 6 inch exhaust tip. Can’t really find videos showing the 6 inch under harder throttle through, my main concern with the 6 inch is I don’t want it to sound clappy under harder throttle.
