I'm about the order a 2011 M3 sedan with ZCP. Like a lot of people, I was trying to decide between a 6MT vs. 7DCT. I have driven both and still can't decide. Since I keep my cars for a while (98 E36 M3 purchased new is now my autocross car), I wanted to know how much would it cost to repair the DCT transmission out of warrantee. My friend and parts manager locally told me that there is no parts available for repairing the DCT. It is similar to other BMW automatic and are replaced when they fail. The cost for a new DCT transmission is approx $13200 and $1200 in labor. In contrast, a manual transmission is $780 in parts. Can anyone confirm or refute this? If this is the case, then I'm buying a 6MT no matter how magical (and it was wonderful on the test drive) the 7DCT. I'm not about to pay 50%+ of the depreciated price of the car to fix it as it matures.
