The Monte Carlo SS Aero Coupe was designed so that Chevy could better compete in racing and a limited number were also built for street use. This ’87 edition has just 6,500 miles on it, suggesting someone stored it away to capitalize on a potential big payout more than 30 years later. We’ll see if that ploy worked when the final bid is submitted here on eBay. Right now, the action stands at $20,700 with an unmet reserve on a car that’s in Londonderry, New Hampshire.

General Motors’ G-bodied intermediates (the Chevy Monte Carlo and Pontiac Grand Prix) weren’t delivering the kind of results in NASCAR they had hoped for. So, for 1986-87, GM fielded “aero coupe” versions of the cars that were “more slippery” than before, but NASCAR required GM to produce a minimum number of them for street use as well. Chevy responded with their version of the Monte Carlo SS Aero Coupe that saw just 200 copies in 1986 and 6,052 (some sources say 3,500) in 1987. In both of those years, Dale Earnhardt won the Winston Cup Championship while driving the car, so the move worked.

While all the ’86 SS Aero Coupes were all built just alike, for ’87 you could get one with any available exterior and interior SS colors. The option code for the 1987 Aerocoupe was Z16, and it looks as though all of them were assembled in Pontiac, Michigan. The SS Aero Coupes featured a fastback-style rear window, rear decklid spoiler, special gauges including a tachometer, and a blacked-out grille. The cars were still rear-wheel-drive and came with a 5.0-liter V8 that produced 180 hp and 240 lb.·ft of torque with an automatic transmission. These were not barn burners compared to muscle cars 15-20 years earlier.

The seller’s SS is a clean automobile with no rust and its original paint, although the finish on the hood, roof, and trunk have begun to fade. It has T-tops with no signs of leakage and the interior appears to be of time capsule quality. The car has seen only 6,500 miles of use, so it’s exceptionally clean everywhere you look. It runs and drives well, but all the belts, hoses, and tires are what it came with from the factory, so anything made of rubber is due to be changed out.

A quick check of resale values for these cars doesn’t bring a consensus other than the range might be between $20-40,000. Let’s say this one sells for $30,000; factoring in inflation for the past 34 years, the original owner would have had to pay no more than $12-12,500 for the car new in 1987 to break even today. But the MSRP for an ’87 SS Aero Coupe without options was $15-16,000. So instead of parking the car at 6,500 miles, you’d have been better off to keep using it, but sparingly.
