I've been thinking about this whole time but I heard the 07' has transmission problem? I found a guy selling his 07 M6 vert in NY for pretty good deal. But maybe it's not necessary. Even the seller told me why am I going from 09 to 07, it's 2 years different. Gas compare to 650i I think it will only has a 500-800 different a year for 15-20k miles/ per year driving? Tires maybe, but will not be a big issue. Maintenance, I did a little research, differential and transmission fluids need to replace more offen, oil change cost higher. No extended warranty. Higher insurance premium. Besides all that I think the feeling hitting WOT on an M6 is amazing.
