This past year, rented a Mini Cooper S while visiting my Mom.
Got the chance to drive one for one week's time.
Best and most fun rental car I've ever had.
Yet when I returned to the GTI when getting back home, it was apparent to me that the GTI was just an overall better car.
Better built, more comfortable, less gimic-y interior, etc.
About the only car I'd replace my current GTI with is the new Golf R
Would like to give a Cayman R a chance though....
