Any advice on 2012 MC Hardtop S?
 

I am about to go and take a look at a low mile example of the mini. Anything I need to look for? What are the common mechanical things that go bad on these cars? Any other suggestions and advice? It's at a dealer in Southern California where I live presently. It's for my wife, her Prius had its catalytic converter stolen right under our noise a week ago. So, she needs a new ride and she is not going to get another Prius for obvious reasons. Any help will be appreciated!
