The 1987 Buick Grand National is a true legend in the American muscle car scene. Known for its bold looks and turbocharged V6 engine, this car became an icon of the 1980s performance era. With its sinister all-black exterior and impressive power, it still commands respect today. However, buying a 1987 Buick Grand National isn’t just about finding one that looks good—it’s about ensuring you get a solid, well-maintained vehicle that lives up to its reputation. Before you invest in this classic, it’s crucial to understand what to inspect, where to look for hidden issues, and how to evaluate its true condition and value.
Understanding the Legacy of the 1987 Buick Grand National
The 1987 Buick Grand National was the final and most powerful model year in the Grand National series. It came equipped with a turbocharged 3.8-liter V6 engine producing 245 horsepower and 355 lb-ft of torque—numbers that made it faster than many V8 muscle cars of its era. It could sprint from 0–60 mph in under five seconds, a remarkable feat for its time. The car’s blacked-out styling, aggressive stance, and reputation as the “Darth Vader” of American cars turned it into a collectible almost instantly. Because of its limited production and cult following, finding a clean and original example has become increasingly difficult and expensive.
Checking the Vehicle’s Authenticity
Before buying a 1987 Buick Grand National, confirm that you’re looking at a genuine model and not a clone. Buick Regal models from the same year can be easily converted to look like a Grand National with the right paint and badges. Always verify the car’s VIN (Vehicle Identification Number). The correct VIN for the Grand National should start with “1G4GJ117” or “1G4GJ11H” depending on the build configuration. Also, check the Service Parts Identification (SPID) label located in the trunk under the carpet—it should include the code “WE2,” which designates the Grand National package.
Inspecting the Body and Exterior Condition
Rust is the number one enemy of any classic car, and the 1987 Buick Grand National is no exception. Begin by inspecting the car’s body panels, especially the lower door edges, wheel wells, trunk floor, and around the windshield. These are common rust-prone areas. Look carefully for signs of body filler or uneven paint, which could indicate previous repairs or hidden damage. Check the alignment of body panels and doors—misalignment might mean the car was involved in an accident. The original factory paint was a specific black finish with a glossy clear coat. If the paint looks dull, uneven, or repainted in spots, ask for records of any repaint work or restoration.
Evaluating the Engine and Performance
The heart of the 1987 Buick Grand National is its turbocharged V6 engine. While robust, it requires proper maintenance to perform reliably. Start the car and listen for any knocking, ticking, or whining noises. The turbocharger should spool smoothly without unusual sounds or smoke. Pay attention to the oil pressure and check for leaks around the valve covers, turbo oil lines, and rear main seal. Inspect the engine bay for aftermarket modifications—many owners upgrade the turbo, intercooler, or fuel system. While some upgrades can improve performance, they might also indicate that the car was driven hard. If you’re aiming for originality, avoid heavily modified cars, as they often lose collector value.
Transmission and Drivetrain Inspection
The 1987 Buick Grand National came with a 200-4R automatic transmission, a unit that can be reliable when maintained correctly but is prone to failure if abused. Check that the transmission fluid is clean and pink, not burnt or dark. When driving, shifts should be firm but not harsh. A delay when engaging gears or slipping during acceleration may indicate internal wear. Also inspect the driveshaft, rear differential, and suspension components for leaks or excessive play. The limited-slip differential, identified by the code “G80,” should be tested by slowly turning in a parking lot—any loud clunks or grinding may signal issues.
Interior Condition and Originality
The interior of the 1987 Buick Grand National is as iconic as its exterior, featuring black and gray two-tone seats, a leather-wrapped steering wheel, and unique Grand National badging. Check the upholstery for wear, tears, or fading, especially on the driver’s seat bolster. Examine the dashboard for cracks, a common problem caused by sun exposure. Ensure that all gauges and electronic components work properly—digital displays, power windows, radio, and air conditioning systems often fail with age. Collectors value cars that retain original interior materials and factory components, so replacements or aftermarket parts can affect resale value.
Electrical System and Electronics
Electrical problems can be frustrating and costly to fix on older vehicles. Inspect all lighting, switches, and controls. The Grand National’s analog and digital instrument clusters are known to develop faults, so confirm that the speedometer, boost gauge, and tachometer function accurately. Test the power antenna and check for any loose or corroded wiring under the dashboard. A well-maintained wiring system reflects good overall care by the previous owner.
Suspension, Steering, and Brakes
The Grand National was known for its straight-line speed rather than handling finesse, but a good suspension setup is still crucial. Inspect shocks, springs, and bushings for signs of wear or leaks. During the test drive, the car should feel solid and not floaty or unstable. Listen for clunks or rattles when going over bumps. Steering should be tight and responsive, not loose. The brake system should also be checked thoroughly—the original Powermaster braking system is a common weak point. If the brake pedal feels hard or inconsistent, it could indicate that the system needs rebuilding or conversion to a vacuum-assisted setup.
Documentation and Vehicle History
A well-documented 1987 Buick Grand National is worth significantly more than one with no paper trail. Ask the seller for maintenance records, previous ownership history, and any receipts for repairs or upgrades. Verify that the odometer reading is consistent with service documents. Low-mileage cars with a full history tend to fetch premium prices, but even higher-mileage examples can be good buys if they’ve been maintained properly. Run a vehicle history report to check for title issues, accidents, or theft records.
Market Value and Pricing Considerations
Prices for the 1987 Buick Grand National have steadily increased due to its rarity and popularity among collectors. As of recent years, clean, original examples can command anywhere between $40,000 and $80,000, depending on mileage, condition, and originality. Modified cars or those in poor condition can be found for less, but they may require extensive restoration. Always compare similar listings, attend classic car auctions, and consult valuation guides before making an offer. Remember that originality and documentation play a massive role in determining true market value.
Common Red Flags to Avoid
When inspecting a potential purchase, beware of cars with mismatched paint, rebuilt titles, or missing identification tags. Avoid vehicles that show signs of heavy drag racing use, such as roll cages, oversized turbos, or slick tires. These cars may have been pushed to their mechanical limits. Be cautious of sellers who can’t provide documentation or who rush you into making a decision. A genuine 1987 Buick Grand National will speak for itself through its condition and paperwork.
Final Thoughts
Owning a 1987 Buick Grand National is more than just buying a car—it’s about preserving a piece of American automotive history. Its combination of turbocharged performance, menacing looks, and limited production makes it one of the most desirable vehicles from the 1980s. However, thorough inspection and research are vital before purchase. Check authenticity, body condition, engine performance, and documentation carefully to ensure you’re investing in the real deal. Whether you plan to drive it on weekends or store it as a collectible, taking the time to evaluate every aspect of the car will ensure your 1987 Buick Grand National remains a powerful and iconic part of automotive heritage for years to come.
