If your looking for an older 911 this is the one to own. Rare, fast and a thumbs up from any other Porsche owner. Unfortunately with the recent up tick in collectible cars this prices the RS at $250,000 or more. If your looking, one is for sale in Europe right now for 320K euros, it is a lightweight vs a Kumfort which are less.
This one sold at Barrett-Jackson in '05 for 95K it was imported from Japan for the auction. Really nice shape unrestored and a good solid driver with about 35,000 km.
Now its a real bargin.
