This white Trans Am Kammback (chassis number 0000EX4796) is fitted with the 190-hp H.O. version of the 305-cu.in. V-8 and a five-speed manual transmission. It reportedly served as an IMSA pace car for a brief period before Pontiac put it into storage. It took Michigan-based Pontiac dealer John McMullen to bust it out of storage and then turn the 36,000-mile prototype over to Scott Tiemann for a complete restoration.
The Kammback them remained in McMullen's collection -- alongside one of the Pininfarina-built Type Ks -- until 2007 when it sold at auction to John O'Quinn for $66,000. Since then, it sold at auction again -- for $44,000 at Barrett-Jackson's 2017 Scottsdale sale -- and ProTeam Corvette Sales has advertised it for $69,995.
