I had a 2008 Cooper for work, did 86000k in 2 years, and it was starting to make some concerning engine rattles, and had lost it's "edge", (it was never thrashed, in fact, never saw redline) so we traded it with 12mth warranty still on it. Whilst it was a fun car, and good promo, I'm sorry to say I don't think they are all they're cracked up to be. Too much plastic to be a "real" mini, despite BMW's efforts to try and align themselves with the classic car brigade. And there is actually more room in my '69 for 4 adults than a new one. Service costs were a joke too.
The thing was diabolical on wet roads, despite having everything checked a couple of times, changing tyres, wheel align etc etc - it would tramtrack, bump steer, torque steer worse than my '69, and aquaplane (heart in the mouth stuff). I thought it was me, but having spoken to a few others they have had the same experiences.
One of the roads I travel regularly has a bump in a corner that I am well aware of - in the new mini hitting that bump would throw the wheel out of my hand and make the car dive to the left every time, seriously, in my new car (Comm Sportwagon) I barely even feel the bump at all.
