1979 Pontiac Firebird Trans Am — Should You Buy One?

Typical asking price: $18,000–$40,000. There is 1 high-severity known issue you need to know before handing over a check.

Kestrel Take

The screaming-chicken Bandit car, and one of the most cloned and modified classics out there. The malaise-era engines are weak but the look is everything. Verify the drivetrain and hunt hard for rust in the notorious T-top and rear-window areas.

What we checked

Checked against public records, 2026-09-25

Federal complaint records thin out badly before about 2000, so there is little here to check against. What follows is our own write-up. Treat a short list as us having less to go on, not as the vehicle having fewer faults.

Known Issues for the 1979 Pontiac Firebird Trans Am

Ranked by wallet impact. These are documented, recurring problems — not freak accidents. How we decide that.

Rust around the T-tops, rear window, and floorsHigh — wallet impact

T-top cars leak and rot around the roof, the rear window channel, the floors, and the trunk. Roof-area rust is difficult, visible repair.

Repair cost (estimate): $3,000-$12,000 — about 41% of what this car is typically worth

Weak or swapped malaise-era engineMedium

The Pontiac 400 and Olds 403 of this era made modest power and many have been swapped. The desirable W72 400 4-speed cars are frequently faked.

Repair cost (estimate): $2,500-$6,000

T-top leaks and interior water damageMedium
