Bought a pretty standard issue '07 328i sedan with heated seats, iPod, and auto... everything else standard. Have owned it for 14 months, haven't had any problems even despite my hesitation in waiting almost 13.8k to get an oil change!! Close to 16k now. Average about 21 mpg with 70% city/30% hwy, and get over 32mpg in pure hwy. Except for the fact that it's a little expensive for what it is, I am thrilled with the driving dynamics, reliability, and quality of the car. If you can afford it, go for it, you won't be disappointed. I didn't get the Sport Package but wish I had - the wheels and seats are awesome!
Sound of engine. Heated seats get hot and stay hot. Door-handle lights at night. Quiet ride on smooth roads. Iconic gauges. Sound of doors closing. Innate quality.
A LITTLE more bang for the buck - I bought this car for the driving experience, not the luxury features or "brand mystique." Still, at $35k wishing I had something like xenons or leather included as standard.
