A 1979 AMC Spirit AMX just surfaced on Bring a Trailer, and it might be the most absurd muscle car proposition of the malaise era: a 5.0-liter V-8 crammed into a subcompact with a 96-inch wheelbase. That’s Trans Am energy in a body roughly the size of a shopping cart.
AMC built the Spirit as a replacement for the Gremlin, which tells you everything about the company’s sense of humor and survival instincts. The base car was a tidy little liftback with four-cylinder or inline-six power, sensible and affordable. But somebody in Kenosha looked at the parts bin, saw a 304-cubic-inch V-8 sitting there, and decided to do something reckless.
The result was the AMX version, exclusive to the liftback body, and it looked exactly like what it was: a compact car trying to fight above its weight class. Hood flames, bold decals, white-letter tires on 14-inch alloys. Pure 1979.
The 304 V-8 made a wheezy 125 horsepower in factory trim, strangled by the emissions equipment of the era. This particular car breathes better thanks to an Edelbrock intake manifold, headers, and a dual exhaust with glasspack mufflers. The transmission is a three-speed automatic, which is arguably the right call when you’re managing that much torque through a wheelbase shorter than most pickup truck beds.
What most people don’t know is that the Spirit AMX had legitimate racing credentials. In 1979, a privateer outfit called Team Highball hauled two V-8 AMXs to the 24 Hours of Nürburgring. It was the first time an American team had competed in that race, and the roster read like a casting call for a Burt Reynolds movie: a one-armed German driving instructor, a Hollywood actor, Lyn St. James before she became an Indy legend, and Jim Downing, the man who invented the HANS device.
The cars won their class. They beat BMWs. And almost nobody in America noticed, because in 1979, the Nürburgring meant nothing to a country that was busy watching Burt Reynolds jump things in a black Firebird.
AMC was always the scrappy one. Too small to compete head-on with GM, Ford, or Chrysler, it survived by being weird, by being cheap, and occasionally by being genuinely clever. The Spirit AMX was all three. It gave you the muscle-car fantasy at a budget price, in a package you could actually park. Only about 3,500 were built for the 1979 model year, and the survival rate has been predictably thin.
This particular car looks sharp in its period-correct livery, the stubby proportions giving it a bulldog stance that bigger pony cars couldn’t replicate. It’s the automotive equivalent of a guy who’s five-foot-six but benches 300 pounds. You might smirk at first, but you’d think twice about cutting it off in traffic.
The auction ends June 24 on Bring a Trailer. In a market where clean Camaros and Trans Ams routinely command six figures, the Spirit AMX remains one of the last genuinely affordable pieces of late-’70s V-8 Americana. The oddballs always get discovered eventually, and this one has a Nürburgring class victory on its résumé, which is more than most garage-queen Pontiac owners can say.
AMC died in 1987, absorbed by Chrysler, its identity scattered to the wind. But cars like this Spirit AMX are proof that the smallest manufacturer in Detroit often had the biggest nerve. A V-8 in a Gremlin successor, sent to Germany to race, wearing hood flames without a trace of irony. That’s not desperation. That’s conviction.
