Engine & Performance
Engine: 3.8-liter turbocharged V6, producing roughly 200-245 horsepower and 300-355 lb-ft of torque depending on the exact model year
Transmission & Drivetrain: 200-4R 4-speed automatic transmission, Rear-Wheel Drive (RWD)

Exterior
Menacing black-on-black color scheme, formal two-door coupe body style, distinct boxy 1980s G-body lines, blacked-out chrome trim, factory turbo-disc wheels or wire wheels, and subtle Grand National badging.
Interior Features
Plush grey and black cloth interior with bucket seats, center console, analog instrumentation with turbo boost gauge, and standard 1980s GM luxury conveniences including air conditioning and power windows.
Condition Assessment
Good. From the visible exterior angles, the body lines appear straight with uniform black paint, though minor aging or weathering typical of driven 1980s classics is expected.
Condition Issues: Possible clear coat fading on horizontal surfaces, minor stone chips, slight wear on driver-side bolster, and potential minor surface corrosion underneath given the era.
Estimated Mileage: 60,000 to 120,000 miles
Historical Significance
The Buick Grand National turned the conservative luxury brand image on its head, proving that a V6 turbo could out-accelerate contemporary V8 muscle cars like the Chevrolet Corvette.
Notable Features
All-black sinister exterior paint scheme named after the NASCAR Winston Cup Grand National series, turbocharged V6 powerplant, and iconic 80s wedge-shaped silhouette.
Production Numbers
Approximately 20,000 to 25,000 total Grand Nationals were built across the 1984 to 1987 model years, with 1987 being the peak production year.
Valuation
Estimated Market Value: $25,000 - $55,000
Auction Estimate: $20,000 - $60,000
Maintenance Recommendations
Regular oil changes with high-zinc or synthetic oil to protect the turbocharger, monitoring the fuel system and turbo plumbing for leaks, and checking rubber suspension bushings.
Fun Facts
1. In 1987, the limited GNX version was actually quicker in the quarter-mile than the Ferrari F40 and Porsche 930 of its era. 2. All Grand Nationals came in one color: black. 3. It marked the final year of the rear-wheel-drive G-body platform for Buick.
