With the third-generation F-body, however, Pontiac designers and engineers apparently saw a less expensive path forward for the Type K’s concept. Where the second-generation F-body used a fixed backlite that, in its latter years, wrapped over onto its sail panels, the third-generation used a massive sloping hatch. The former required extensive sheetmetal modifications to generate a station wagon; the latter required only that the hatch be swapped out for a taller and squared-off wagon version (much like the Nissan Pulsar NX, which entered production in 1986).
And that’s just what Pontiac’s designers did in 1985. The result, which Pontiac called the Kammback this time around, didn’t quite have the length of the Type K, but it did include the Type K’s gullwing glass panels. While most sources indicate Pontiac built just two Kammbacks — a black version and a white version — contemporary photos show a third in red. Motor Trend, which included the black version on its August 1985 cover, reported that the Kammback option would cost just a few hundred dollars and be available as a dealership-installed accessory to ensure quality control.
The white Trans Am Kammback (chassis number 0000EX4796), fitted with the 190-hp H.O. version of the 305-cu.in. V-8 and a five-speed manual transmission, 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 full 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. No pre-auction estimate has been released for its upcoming trip across the block at Mecum’s Kissimmee auction, slated for January 3 to 13.
