I purchased my 2007 BMW M6 Convertible about 10 months ago. I decided to hold off on submitting my review until now because I like to form a close relationship with my vehicle before singing its accolades. Well, all I can say is that this car has exceeded all my expectations. It is simply the best car I have ever owned, bar none. The car is an absolute blast to drive. For the first time, I actually look forward to getting up in the morning to drive the 20 miles to my office. Same applies to my drive home from work. The V10 engine is sublime. The handling is confidence-inspiring. The build quality is second to none. As far as the iDrive and SMG are concerned, I love them both.
I was excited when my dealer told me a new black M6 convertible was in stock so I rushed out to get this baby. About a month of ownership later, I am so disappointed with this car that I may burn my BMW fan club card. I'm close to swearing off BMWs and giving Mercedes or Lexus a try. I loved BMWs in the first place due to their engineering, reliability, style, and service. So far, the M6C's engineering is questionable, reliability pitiful, style passable, and though the BMW service is superb, it has nothing to do with the physical car itself! My new M6C has been in the shop 4x in the last month and needless to say, it's the most unreliable BMW I've ever purchased; and I've owned 6 so far.
I've had many Bimmers, but the M6 is absolutely incredible. You can't drive it without a smile on your face!!! Great power, more than I can ever possibly put to use... not that it isn't fun to get on it! Yet it feels very solid. I was going to go porsche turbo, but the M6 is much less jumpy and it's more comfortable. And I didn't buy it to race, so I like the extra room. If you like BMW, you're gonna love this car!!
This car craves the autobahn. I am consistently going 10 to 20 mph over the speed limit w/o meaning to. The car seems to idle @ 70 mph. Great power, I would like to change the rear end to a Dinan3.91 for better low end speed. I love this car. Gas mileage as one would expect is horrible, but that goes with the 500 hp territory.
