No t-top on this one. My 86 Z-28 had them. Never had problems. Although I have heard that the second gen Trans Am's had leaking issues from the t-tops.
Cool car Cougs. The drug dealers were riding these in my neighborhood when I was a wee Frenchie.
(My Dad had a Grand Marquis. My brother and I were carsick for years, until he made the switch to a car that didn't have marshmallow for shock absorbers.)
Generation 2 Trans Am's/Camaro's (from what I hear) are the next big thing in classic cars. In fact, I am probably behind the curve here considering I believe it has to be 25 years old to be considered a "classic".
GTO's, Chevelle's, Barracuda's those are some pricey ones.
Actually anything that's really rare is expensive, and the more rare the more expensive. Obviously condition does matter, but not for some cars. If they only made 9 of something it could look like a rusty Pinto and be worth a bundle.
