While I have not owned my used Cooper convertible very long, I've been looking for 3 years. It was babied in the first 44K miles. It's a dream to drive. 5 speed shifts like new, handles better than anything I've owned (38 cars and counting).
Stereo is wonderful. It has the sport package so the ride is a bit stiffer than standard MINI but not unbearable, plus it handles like a dream.
