Pontiac Fiero GT *Supercharged 3.8L Engine*

1987 Pontiac Fiero GT
Supercharged/Intercooled

Sounds of the powerful engine and supercharger, thrills of the road, and constant looks. Maximizing power, reliability, and overall cool factor, you are viewing one of the best Fieros out there. This Fiero holds nothing back and has the looks of a show car. Some paint chipping on ground effects, but for a 30 year old car the paint has held up really nicely.
