1987 CHEVROLET MONTE CARLO SS “AEROCOUPE” #1G1GZ11G4hHP139842. (Stock #4092.) When General Motors needed to build a car to compete against Ford on 1980's Nascar race tracks, they chose their Monte Carlo which had been introduced in 1970 as a personal luxury car. Modifications had to be made to the "SS” body to make the car more wind-efficient and this led to the unusual rear-end and window design. To be race legal with Nascar, the car had to be “homologated” by GM building a set number of the model for legal road use. This homologated model became the limited production, road going “Aerocoupe.” The 305 "H.O.' (High Output) V-8 engine with a 4-speed Turbo Hydramatic transmission, with a floor shift, and a 3.71:1 differential resulted in a delightful driveline for the car. Our car was purchased from its original owner 12 years ago, then with 73,250 miles. Its second and only other owner purchased the car for very limited show use and brought an extremely nice and original car to near-concours condition. He purchased a set of four chrome Crager wheels but saved the original ones with the car. Finished in black with a tan interior featuring front bucket seats, the car is-- aside from the wheels, added under hood air horns and a upgraded stereo--completely stock and original. The car drives exactly as it should and features electric windows and ice-cold air conditioning. Amazingly nice condition throughout. 75,280 miles. $21,500.
