Come on now guys, do you beat on a loaner any more than you would your own? If your an aggressive (maybe I should say enthusiastic?) driver, then you are going to drive about the same if your in your own car or a loaner. BMW's are meant to be driven, and driven hard. I would be surprised to see some sort of study that said loaner cars are less reliable than non-loaner cars. All of that said, my dealership only has base 328i auto's for loaners, not something I would be interested in anyway...
