I've been working on buying a new car recently. I'm going to buy a BMW Z4. As part of this I've started learning as much as I can so that I pick the right options (and the right car!) and get a good deal. As part of this I've been reading the online forums up at roadfly.
BMW seems to have great customer service! Check out this thread. This guy is having problems with the SMG transmission on his car. (SMG is "Sequential Manual Gearbox" and is similar to an F1 race car transmission) Notice this response from a BMW customer service rep.
I wish that we could give this type of support for Windows. Perhaps if we charged $40k a copy we could :)
