Mine is this (will never be able to afford one, but it's the one car I'd want to drive if given the chance) - in the exact color combination shown:
When it comes to racing sims I've always chosen the 911 RSR's... I love their nice revving normally aspirated motors and the way they handle and brake. Easy to be consistent as the fuel and tires wear down... would love to drive one on the track for real...fits my driving style of just banging out laps with precision and fun at the same time.
