In an attempt to take the NASCAR Cup home, General Motors designed a pair of cars in 1986.
The Chevrolet Monte Carlo Aerocoupe and Pontiac Grand Prix 2+2 were built for speed with unique noses and unusual fastback rear windows for improved performance on the racetrack.
Donated to the International Motorsports Hall of Fame in Alabama, the car will be auctioned at the Mecum Auctions event in Kissimmee, Florida.
Although it is tough to pin down a number, the silver cars usually sell in the $20,000 range.
