I bought my Cooper Hatchback used with 13.4k miles, and I absolutely love it. Yes, it's a little on the loud side, and rough roads make for a bumpy ride. But this is absolutely "the most fun" car I have ever driven! It absolutely hugs the road - I love putting the sunroof down (and the seat heaters on if it's chilly) on a sunny day, especially if I have the luxury of a drive across the back roads. However, I live in an urban area, and most of my driving is a rush-hour commute. I still wouldn't change the car. I get about 27 MPG in town (bumper-to-bumper) and 33 MPG on the highway.
Incredible control on curvy roads, plus the sunroof and seat heaters.
It is a little loud, and it would be nice if potholes weren't so noticeable.
