11k enjoyable miles.
A a few problems, had AC belt and tensionors for the dreaded SQUEAL and it's still squealing. A couple of elec glitches.
Like stated above it's a blast to drive, deceptively fast. Like maswastage I am not a street racer but I've had a couple of run-ins with some other cars and the d took care of business. First was a 335i convert from a dig running stock, had him by 2 cars up to about 100. Second was a '10 S63 AMG from a dig runnning the JBD, had him by a car length from the start up to about 100 mph.
I've been very impressed so far, but I will be interested to see how well our cars/dpf systems hold up over the long haul. I had intentions of keeping this car for a while, but if the dpf system proves to be problematic I will reevaluate my plans.
