Hey Paul, if its going to be a car for the rest of your life, I'd suppose it would have to last for a long time. But say you have some problems with the car I'll pay to repair it. Now what would you take??
Chris, the 456M isn't bad looking either. Probably one of the best looking 2+2 cars I know of to date. It isn't the 550, but it isn't all that bad.
