I had an 2003 V8 purchased 6 months old and put 75,000 miles on it in a little over a year. To this day, the best snow car I've owned/driven. Something about the PSM that is better than even Audi's system. Unbeatable vehicle for slogging it out in comfort and safety on crappy snow-ice-slop covered highways. Also did some 'ice racing' in an '04 Turbo and it seemed to defy the laws of physics for such a heavy vehicle- lots of fun!
Yes, MPG will be worse than you can imagine.
