The 1987 Buick Grand National remains one of the most recognizable turbocharged performance cars of the 1980s. Finished in black with the intercooled 3.8-liter (LC2) turbo V6, these G-body coupes still draw strong interest from collectors, drivers, and buyers seeking financing or insurance coverage.

This guide covers current market values, the factors that move price the most, common issues that reduce value, and practical tips for bank loans and insurance appraisals.

Current Market Values for the 1987 Grand National

Values vary widely based on condition, mileage, originality, and documentation. As of late 2026:

• Classic.com Market Benchmark (CMB) for the 1987 Grand National sits near $48,000–$49,000.
• Hagerty Valuation Tools typically places a #3 (Good) condition example in the low-to-mid $40,000s, with stronger examples higher.
• Recent auction and private sales for driver-quality cars with 50,000–90,000 miles commonly fall in the $35,000–$55,000 range.
• Lower-mileage, highly original, or well-documented examples regularly sell in the $60,000–$75,000+ range.
• Modified or project cars can sell for less than $30,000.

These figures are benchmarks only. Actual fair market value for a specific vehicle depends on its condition, history, and recent comparable sales.

What Affects Grand National Value the Most

Several factors consistently move the needle on these cars:

Originality and Matching Numbers

Cars that retain the original turbo engine, transmission, and major components typically command a premium. Documented numbers-matching examples with supporting paperwork sell stronger than cars with swapped powertrains or incomplete records.

Turbo System and Mechanical Condition

The 3.8-liter turbo is the heart of the car. Buyers and appraisers look for evidence of proper maintenance, a healthy turbo, intercooler integrity, and no major oil leaks or boost issues. Recent service records on the turbo system add value; deferred maintenance reduces it.

Mileage and Condition

Lower mileage helps, but condition matters more. A well-maintained higher-mileage car in solid driver condition often outsells a neglected low-mileage example. Paint quality, interior wear (especially the distinctive cloth seats), body integrity, and absence of rust all factor in.

Documentation and History

Window stickers, service records, ownership history, and clean Carfax or AutoCheck reports strengthen value. Cars with known one- or two-owner histories or documented restorations tend to appraise higher.

Modifications

Period-correct or tasteful upgrades can be neutral or mildly positive if well executed and reversible. Heavy modifications, non-original interiors, or extensive aftermarket turbo work usually reduce value for collectors and many lenders.

Common Issues That Lower Value

• Prior collision damage or poor repairs
• Non-original engines or major drivetrain swaps
• Deferred maintenance on the turbo, fuel system, or cooling system
• Title brands or incomplete history
• Significant interior or exterior wear beyond normal use
• Missing original components (seats, trim, wheels, etc.)

A pre-purchase inspection is strongly recommended before buying, especially on cars listed online or from private parties.

Financing and Loan Appraisals for Grand Nationals

Many banks and credit unions will finance classic cars, including Grand Nationals, when a certified appraisal supports the loan amount. Lenders typically look for:

• A current fair market value opinion based on comparable sales
• Clear documentation of condition and mileage
• A clean or acceptable title
• Loan-to-value ratios that leave equity in the vehicle

Online certified appraisals (photo-based) are widely accepted for loan collateral on these cars when the report is prepared to professional standards. In-person inspections are preferred for higher-value or heavily modified examples.

Insurance Considerations

Agreed-value or stated-value policies through collector carriers (including Hagerty and others) usually require a current appraisal. A certified report that reflects actual market value — rather than a generic book value — helps ensure proper coverage and reduces the chance of under-settlement after a loss.

Bottom Line

The 1987 Buick Grand National continues to hold strong collector interest. Driver-quality examples typically trade in the mid-$30,000s to mid-$50,000s, while better-documented, lower-mileage cars command more. Condition, originality, turbo health, and paperwork matter more than any single price guide number.

Whether you are buying, selling, financing, or insuring a Grand National, a certified appraisal based on recent comparable sales provides the most defensible value.
