I found a 99 r6 with 14,000 miles that is in excellent shape, almost perfect. It has a D&D exhaust, undertail, some carbon fiber accents, flush mount signals, and a new tire. The guy wants $4000 for it. Is this a good deal, or should I stay away because of the mileage? What is high mileage on a sportbike? What is 100,000 miles on a car compared to a bike? thanks for all the help..
