2013 BMW 335i. Super fast, great transmission, high quality materials, but absolutely horrendous build quality. Everything rattled and made noises, fixed probably 20 rattles myself and had to go to the extremely uncooperative dealer about a few more, and I was never able to fix a few of them. Drove me fking insane. It was also a very intense car to drive, with the stock staggered 19'' summer runflats, and generally hard to grasp dimensions of the car. My wife did not enjoy driving it. Great high speed cruiser for our road trips between SF and LA.
Much happier with my LR RWD Model 3.
