My Mini is a Cooper S, meaning it's supercharged (i.e. can go fast, quickly!) and also has a man-umatic option. There's a double sunroof, leather seats, and the interior is spotless. I love my car because it's incredibly fun to drive (it's very zippy!), handles easily, and gets awesome gas mileage for a supercharged vehicle. BMW manufactures MINIs, so the quality of driving is wonderful, the user interface (console/gauges) is very pleasing, and the speakers are great for loud music ;).
While the interior is small, there is plenty of leg room for tall drivers and front seat passengers. There isn't very much boot (trunk) space but the rear seats do fold down. If you're looking to test out a car you may one day want to buy, give mine a go!
