I've only owned my 2007 Cooper for a month but, wow what a fun and surprisingly functional car. The interior choices guarantee individuality unheard of at this price. Its fuel economy has been 30 mpg in city driving, and near 40 mpg highway. The build quality is excellent with no unsightly gaps ect. The sport seats are comfortable even for a couple of hours without fatigue!
The Steptronic automatic transmission is very smooth and with the manual mode very fun also. The good gas mileage!
