In 2015, this custom 1977 Pontiac Firebird Trans Am Shooting Brake appeared on eBay and had bids reaching $4,150 in the final hours.
This breadvan is powered by a 400 cubic inch Pontiac V8 that was emissions choked down to 180 horsepower and 325 ft-lbs of torque. Performance with a stock 400 and slushbox transmission will be lackluster but uncorked, they can make plenty of power and noise.
