First thing, a 6 speed with at least the 6.1 motor then a good sized from air dam amd duck tail spoiler. I am assuming the weight will be less than the prototype too. For the performance versions maximum 18" wheels with good summer tires. I like the black hood with pins too, make that an option. A good exhaust is necessary too, side pipes like the T/A would be cool. And I almost forgot big brakes.
On the interior plain is best. Good non-power seats with lots of support, no nav system or anything like that and a base AM/FM/CD.
The more I see of the T/As, the better I like them. They weren't the fastest but they were better balanced and looked tough.
