I agree that most buyers for a MS3 would rather buy new due to the type of car it is. BUT not everyone can afford a new MS3. My asking price of 23,000 is coming with a 7yr/75k mile warranty...... I dunno about the other guy here, but I know that the extended warranty should have enough time/mileage to cover the next owner , maybe the next 2 owners.
As for break in and caring what people did, in the end it doesn't matter , why cause you'll never know how someone drove the car. Anyone would be a fool to believe that any current owner of the car has babied up until now. come on, people we buy these cars to drive and have a great time with.
If you have the money to buy new by all means do it, IMO 23k is reasonable, especially for a car with a 7yr extended warranty . 22k ish for a car that doesn't have an extended warranty is still reasonable. why..... cause its still cheaper than buying a NEW SPORT MODEL. and has all the extra goodies.
