1990 Pontiac Sunfire
Oh, if only Pontiac just had the confidence to release it to the public! The Sunfire was a great concept car with awesome technology and looks. It is too bad that the company got cold feet and shelved it in 1990. Five years after that, Pontiac released a safe and unexciting Sunfire instead. What a shame.
1986 Pontiac Trans Sport
In 1986, the company joined the NASA bandwagon and made a concept car that looked like a spaceship! The Trans Sport is a family van whose concept was received positively, so it was odd that Pontiac did not follow through. In the end, it released a watered-down version of the Trans Sport. Few of the original features made it to the actual model since most of them were too expensive to add.
