Just picked up my 2007 CPO. Love it so far. Was a toss up between the 335 and the 328. The 328 has MORE than enough power and is naturally aspirated = will last longer, so I went with it. Opted for the base model (leatherette, non-sports seats, normal radio, 16-inch wheels) and as a car nut, I gotta say I love it, even without the bells and whistles. Manual transmission is silky smooth, and the car feels like it's on rails. The car just feels well put together and tight, at least compared to my 9-5 Aero which was creaky and loose. Can't beat the BMW CPO program either. Bought the maintenance pkg for $1500, won't sink a dime into this car for the next 5 years.
Acceleration, silky smooth gear box, surprisingly good gas mileage
Stock wheels are kind of frumpy. Should at least have 17" on it. Also stock floor mats get caught on long clutch throws.
