That isn't right
I have to agree, the Pontiac T/A was the star of that show. Bringing it back with a stand in (even though it is a really cool Mustang) is pretty cheesey. They could have made the movie even cheesier if they re-cast David Hasselhoff as the star and driver.
For my generation, it won't fly. There are some things you just don't mess with.
Burt Reynolds in Smokey and the Bandit drives a black Trans Am.
The Duke boys drive an orange Dodge Charger.
Doc Brown drives a Delorean.
Professor Fate drives a Hannibal 8
