30. Pontiac Firebird Trans Am
In 1969, Pontiac wanted to present a model they could homologate for Trans Am racing. As a part of GM, the factory was still under the racing ban. So, to mask its intentions, Pontiac introduced the Firebird Trans Am as a loaded version that featured big-block power from the famous 400 V8 engine equipped with Ram Air III or IV intake system.
However, this special version with signature white paint, blue stripes, Rally II wheels, and other equipment proved to be a tough seller. Unfortunately, they only sold 634 Firebird Trans Ams. And among those, only eight were convertibles.
