Hello everyone! I've recently been window shopping cars, and stumbled upon a seemingly good deal on a 2006 M6. The car is listed for 29,000 and only has 25k miles on it. I was just curious about the real cost to own these cars though before inquiring about the vehicle. Now, I currently own a 2006 GTO which so far I happen to love and have yet to have any problems with. Maintenance costs have been minimal other than changing oil and fluids. I've had the car almost two years and I've only put about 6k miles on it. How much more expensive would it be to own an M6? Also, since it is a low mileage vehicle from a dealer, how much would warranty cover these costs? I've purchased all my cars privately before, so this is something I am unfamiliar with.
