Hi Steve,
Glad you checked back in!
22,000 miles so far with original clutch, but no more hauling my friends around going uphill at full load. (Don't you want to ask about oil consumption too?)
I had a buyer awile back for my Avus Blue too, but turned him down. He came down for the winter from New York (don't they all

) and seemed to be itching to get an Avus M5 as soon as he arrived. I just can't part with my limited edition baby.
I'm getting ready to replace my Pilot Sports (ouch $$$) but can't complain at 22k with 2 or 3 track days and excellent performance all the way. Except for the price, they seem to be the perfect overall setup.
Keep us posted on your M5 progress. Who knows, maybe you'll run across your blue car back in the classifeds at just the right time!
