I'm thinking about selling my 2010 M5, and would like some input on price. It's Black/Black, oil change every 7500, has a new clutch/flywheel, and is an SMG, with the downside of having 85k miles. Oddly enough, and to my surprise, I haven't had really an issue with the car (and I'm super picky and hear/feel/see everything). I purchased an extended warranty and never used it once until the very end of the warranty when I managed to get the flywheel replaced (I paid for clutch). After reading horror stories about issues with this car I was expecting the worst, but have to admit it's the best car with the least amount of problems I've ever had. So question is, what do you think I could sell it for?
