I also have a red 88 M6 with 111,000 miles. I love the car...paid 13M one year ago w/90,000 miles. If I were to sell it today, I would expect locally(Little Rock) to bring around 10M. And this is after I've added 17"BBS wheels and tires and a new OEM exhaust. It takes someone in the know to spring the $ to buy one of these. 1988 is an OLD CAR to most people. It is a pleasure to own and drive an M6 each day. my .02
