I have 8400 miles on it. No complaints, have run the car at Laguna Seca and Infinion Raceways. Powers out of curves like no other car in existence. Needs Michelin Cup tires instead of PS2 for track days. Most fun I've ever had driving a car, build quality the best. Ordered 22 options, which are expensive, but this is my last purchase for retirement so thought it worth it.
4 WD, sound from sport exhaust, babe magnet.
Needs an iPod input which will appear in the 2009 models. Forget the navigation system, it will be outmoded in 6 months and is complicated. Get a portable Magellan or Garmin GPS, and definitely a Valentine One radar detector!
I just bought this car a week ago after owning 4 other 911's. This is my 1st C4. Add ons: 20' Champion wheels, Aero kit, suspension. The AWD is worth the money. I live in a mountain community with a lot of winding roads. The car handles great. Definite improvements since 2005.
