Buick GNX runs 0-60 in 4.7 seconds, Corvette gets the 16-valve L98, and the Fox body Mustang GT peaks at 225 horsepower

1987 is the year the Buick GNX happened. ASC and McLaren built 547 of them from leftover 1987 Grand National bodies, and each one got a revised turbocharger, intercooler, and transmission tuning that pushed output to a conservatively rated 276 horsepower. Conservative is the right word. Road tests at the time suggested closer to 300 horsepower. The GNX ran 0-60 in an estimated 4.7 seconds. That was faster than a Ferrari Testarossa in contemporary comparisons. Buick. Let that sit.

Ford pushed the Mustang GT 5.0 H.O. to 225 horsepower for 1987 through revised cylinder heads and better tuning of the multi-port injection system. The Fox body had found its form. The GT was a legitimate performance car at a price working people could afford. A new GT hatchback stickered around $10,400. The aftermarket was growing fast, and the performance ceiling for these cars was being pushed higher every year.

The Corvette got the refined L98 engine producing 240 horsepower and added optional Z52 sport handling. The C4 was maturing. A twin-cam ZR-1 was in development and word was getting around. Smart buyers in 1987 knew the next Corvette was going to be something serious, which cooled enthusiasm for the current car slightly. That made 1987 C4s available at realistic prices then and still somewhat reasonable today.

1987 in automotive history
  • Buick and ASC/McLaren produced exactly 547 GNX units for 1987 with a revised Garrett turbocharger, low-restriction intercooler, and modified TH200-4R transmission, officially rated at 276 horsepower but independently tested at outputs closer to 300 horsepower, with 0-60 times estimated at 4.7 seconds.
  • Ford raised Mustang GT 5.0 H.O. output to 225 horsepower for 1987 through revised cylinder heads with better port flow, while holding the base GT hatchback price at approximately $10,400, making it the highest-value performance car per dollar in the American market.
  • Chevrolet introduced the Camaro IROC-Z convertible for 1987 with a 5.7-liter tuned-port injection V8 rated at 220 horsepower, the first Camaro convertible since 1969, with production limited to roughly 1,007 units in the first year.

Market: The GNX is now a blue-chip collectible with prices ranging from $120,000 to over $200,000 for low-mileage documented examples. Standard 1987 Grand Nationals trade between $40,000 and $70,000 for clean originals. The 1987 Camaro IROC-Z convertible has climbed to $25,000 to $45,000 given its low production and the open-air factor.

Buyer's note: On any GNX transaction, require a full ownership history, original window sticker, and confirmation of the unique GNX-specific engine and drivetrain components, as the cars have been heavily scrutinized for fraud and component swaps since values climbed above six figures.
