I have had my Mini for about a year and a half. The car has been fantastic, perfectly reliable, a real blast to drive and is quite efficient. I had debated long and hard about getting the S version; however, I have no regrets. The car is super quick, very powerful, and I get about 38-42 MPG depending on how fast drive.
Agility, acceleration, fun appearance, quirky interior, brakes, fuel efficiency.
