Don’t sell the e46. You will regret it I did the same thing got a f87 M2 comp but I kept the e46. The sound of the s54 at 8k rpm the s55 doesn’t have the same sound. They are two different cars. If you can I recommend holding on to the e46. I put a Eonon android head unit. It looks like the factory nav unit but it has everything you want on it. It has navigation and car play and the steering wheel controls even work with it. I also got a backup camera that works great especially with the parktronic system. When I got the M2 it really made the M3 feel dated. With that head unit install it gave me all the functionality of the M2 except for I Drive. I plan on keeping the e46 as long as possible.

03 Thats what is in the driveway.

I had an identical one years ago. Same color scheme instead of your wheels I had BBS with blue center and polished lips. I painted them black myself. And I had US bumpers but I painted the rubber body color like the e30 convertible.
