I have the good fortune to have this coupe "consigned" to me. It's been lovingly cared for by the same owner since new. Carfax shows 3-owners, but they are all the seller and her ex-husband. AutoCheck has it right.
It spent it's first 6 years in California before relocating to the Denver area in 2006. Therefore the undercarriage is remarkably clean and looks much better than my own coupe which was originally in the northeast.
This M Coupe is almost entirely stock aside from the OEM daytime-running light module. It has been regularly serviced at BMW dealers or well-known independent shops, and it has every record to prove it. The tires are only 1.5 years old and have just 3,500 miles on them.
Aesthetically, it's in great shape. The driver seat bolster looks great with just a couple minor creases and no visible wear marks. The only minor ding I could find is in the middle of the driver door, but you have to look for it. Each of the wheels has some curb rash though.
The only black mark against it is an accident when it was less than a year old. The bumper, hood, radiator, and fan were replaced by a BMW dealer with factory parts. The accident is not on either Carfax or AutoCheck, and all documentation and photos will be provided.
