1987 Buick Grand National — Should You Buy One?

Typical asking price: $30,000–$75,000. There is 1 high-severity known issue you need to know before handing over a check.

Kestrel Take

The turbocharged black sleeper that humbled Ferraris in its day and now trades like the icon it became. The turbo V6 is strong but aging, and originality commands enormous premiums. Verify it is a real GN and not a dressed-up Regal, and budget for turbo-era maintenance.

What we checked

No public record to reconcile against

We don't yet have a public record to check this one against. Federal complaint records thin out badly on older vehicles, so there is little to check against. What follows is our own write-up, and it has not been reconciled against an official record. Treat it as a starting point, not a verdict.

Known Issues for the 1987 Buick Grand National

Ranked by wallet impact. These are documented, recurring problems — not freak accidents.

Aging turbocharger and fuel systemHigh — wallet impact

The turbo, intercooler, fuel pump, and injectors are decades old. Many have been rebuilt or upgraded; an unmolested original may need all of it.

Repair cost (estimate): $1,500-$5,000

Source: not yet checked against public records.

Cloned or misrepresented GN/T-type identityMedium

Regals and T-types get dressed up as Grand Nationals. Verify the VIN, options, and documentation before paying GN prices.

Repair cost: Not a repair — an ownership-cost warning, not a mechanical fault

Source: not yet checked against public records.

Rust in the T-top area, trunk, and floorsMedium

G-body rust at the roof (on T-top cars), trunk, and floors.

Repair cost (estimate): $1,500-$6,000

Source: not yet checked against public records.

Deteriorated original interior and electronicsMedium

Digital dash, interior plastics, and trim degrade and are hard to source correctly.

Source: not yet checked against public records.
