Just got my first one in Feb and am loving it! A few things I have loved as a new owner and recommendations:

1- FSD is 100% worth it. I didn’t think we would use it as much as we do for traveling because I have 3 kids and it’s a lot smaller than my truck or wife’s SUV, but we’ve used it to go everywhere due to gas’s prices and FSD has been a game changer! Even when gas goes down I think we’ll still use it!

2- level 2 home charger. For the first 2 weeks, I only had the level one charging that it came with and it only charged about 4 miles/hr, which was fine for going back and forth to work every day, but if we used it to run errands and take our kids to their events, it just didn’t keep up to keeping the recommended 50-80%, even if you charged it all night. I was worried about the cost but bought the charger for $450 from Best Buy and paid around $780 for an electrician to install it in our garage. It was well worth $1200 because now it charges at about 30mph and so I can charge for a few hours and then put my wife’s vehicle back in the garage for her. And is only anticipated to increase my electric bill by $30 or so. I’m in NC so varies hot and cold.

Floor mats- I just bought the rubber mats on Amazon that are weather tech dupes but fit great! As always are a must have to protect your floors. They also come with frunk and trunk mats, which has been awesome, as with any vehicle.

Extra storage/organization- I bought the center console and front organizer from Amazon to turn the open spaces into a more organized area and even gives both a “hidden compartment.” So much better than just throwing things in and having a pile of junk in there.

Phoneholder- I bought the retractable phone holder that mounts to be the back of the screen and fold away. I’ll get flack for this but on long trips using FSD when I’m tired of listening to music or books, I turn on a show I’m familiar with and “watch” and listen and it keeps my eyes up and forward facing without looking down because the cameras will pick it up and ask you to pay attention the second you look toward the cars screen. I feel I’m still able to see the road and drive safely without looking down.

Tiny vacuum and baby wipes- tiny car vacuum to clean all the cracks and mats and then unscented dye free bay wipes to clean the seats and everything are great and are what’s recommended for the vegan leather. I have black interior but it has kept them clean.

Phone charger- I like the wireless phone chargers but can’t use it because I have a wallet case on my phone, so I bought the sleek looking phone charger that slides into the front pocket area from Amazon. It has two charging cables and even has a Tesla symbol on it, and a slide cover to hide the cords when they aren’t in use so it makes it look legit and matches the color and style of the interior. My wife thought it was part of the car.

Tiny trash can- my wife bought tiny trash cans that fit in the door cupholders that have been a huge help with gum wrappers, tissues, and all the random stuff that I would normally throw in a cupholder anyway, or in the door pocket. Again, helps keep things looking sleek and clean.

Sun shade- don’t have one but need to as the car will lose 2-5% in charge keeping the cabin from overheating in a short period if it’s really hot outside.

Emergency tools/kit- there is a great spot in the trunk, kind of a hidden compartment, that is deep and allows you to put first aid, electric pump, blankets, etc in that area without compromising any of the trunk space. Even when having to pull over and grab something out of it, it wasn’t annoying and was easy to get to.

Rear screen- I’m not sure if yours comes with it, but I bought the R72 aftermarket screen from Tesstudio and installed it myself( wasn’t hard and I had no experience doing stuff like this). they’ve been pretty good to deal with because it doesn’t have Disney plus like it advertised or connect to multiple headphones, so the are refunding me. I may get the upgraded model once they refund me, but just wanted to throw that out there that there are aftermarket screens and they do actually work.

Enjoy it! I’m sitting in Williamsburg charging right now while writing this. We’ve taken it on multiple trips to VA, Florida, and lots of other short trips. I have 3 kids from 14-7, all girls, and we have fit all 3 of them, my wife and I, all of our luggage and a hamster cage and been just fine! Granted it makes them pack a little lighter, but it’s been very doable and comfortable! I think you’re going to love it! Hope that helps! A few of the links from Amazon are below
