1989 Pontiac Optima GSI Turbo

Not too many people ever modify this car, as it was never not too popular in North America. With great European heritage as Opel Kadett and Vauxhall Astra GTE, I wanted to build something original, something no one did before. The car was given Euro look, including the European front bumper, Cosworth-style rear wing and most importantly the 2.0 turbocharged engine.
