Rare RWB Porsche and High-Mileage 911 Among Five Collector Cars Listed

Five collectible performance cars illustrate the breadth of today’s enthusiast market, from classic air-cooled Porsches to modern track machines and American muscle. A 1990 Porsche 911 Carrera 2 converted by Akira Nakai into the rare RWB “Tenka Gomen” is listed at $115,000, with its provenance and unusual widebody supporting an estimated final value around $130,000 to $230,000, though the stock 82,000-mile engine warrants testing. A high-mileage 1982 Porsche 911 SC is being offered for about $73,000, showing how even relatively ordinary, well-kept air-cooled 911s command substantial prices. At the opposite end of the Porsche market, a black 992-generation 911 GT3 RS with both the Weissach and Manthey packages has reached $400,000, with its former marketing and track-use history and registration status tempering an estimated value of $380,000 to $480,000. Rounding out the listings are an exceptionally rare, 8,000-mile 2005 Dodge Viper Copperhead Edition and a restored 1968 Shelby Mustang GT500KR convertible, whose limited production, original specifications, and powerful drivetrains place them firmly in the high-end collector market.
