1989 Pontiac Turbo Trans Am 20th Anniversary with 29,723 miles, one of 1,555 built

Why we picked it

Motorcar Classics in Farmingdale, New York lists this white 1989 Turbo Trans Am with a tan cloth interior for $39,900 and is open to offers. The dealer says it is unmodified, with the original drivetrain and finishes. The VIN shows the 3.8-liter turbo V6, the Buick engine Pontiac put in the 20th Anniversary car.

The price is in line with recent sales, so it is not a discount. We picked it because only 1,555 were built, and mid-mileage cars that are still stock are hard to find. The mileage is high enough that you can drive it without hurting its value much.

The value check

The seller is asking $39,900. Comparable cars in the same condition have sold for $37,001–$45,050, so the middle of the market is about $41,025.50. That put this car 3% under.

Turbo Trans Ams with 9k-62k miles sold for $37,001 to $45,050 on BaT in 2026, and a 29k-mile car brought $43,050 on PCARMARKET in January 2026. The $39,900 asking price is fair for the mileage, not a discount; we picked it for its rarity.

• Turbotransam.com auction results

What to check

• The listing does not mention service records or title status; ask for both, plus the window sticker or PHS documentation if available
• The dealer's page gives the mileage as both 29,723 and 29,732; confirm the odometer reading
• Check the turbo for oil seepage and shaft play, and check the intercooler plumbing and the condition of the factory MAF and boost hoses
• Inspect the T-top seals and the Pace Car interior trim and decals, which are expensive to replace correctly
• Look for rust at the hatch, the rear wheel arches and the lower doors, and check the dash and seats for UV damage

Making it drive like new

Keep it stock to protect the value. Small, reversible updates such as fresh tires, new fuel and brake hoses, and a careful service of the turbo oil lines and cooling system make sense; save chip tunes and bigger turbos for a less rare car.
