2007 BMW 3 Series Coupe 335i 2dr Coupe (3.0L 6cyl Turbo 6M)
335i + JB4=Super Car
 Had an 06 550i and after reading the reviews, I went ahead and got a black/black with 6 speed. Had her for a month. RFTs are abysmal, changed to Michelin Pilot Super Sports. Wow what a difference. Quieter and grip feels like it's doubled. Also installed a JB4 module. She now has an extra 100 hp and 100lbs of torque at the crank. M3 fast and gas mileage is wayyyy better city driving (19 vs 12). Seats are comfortable, miss the 20 way power seats of the 5 though. Used to the Idrive (use voice). Sound system is ok. I'm dreading the unnecessary trips to the dealer, but for 28k plus an extra 1600 in upgrades I gotta car that is stupid fast, fuel efficient, luxurious, and inconspicous.
