Boy, this is really weird.
I post a lot of F-body boards, and one thing a lot of people have in common there is that they SWEAR by their T-tops! Sure, there are people that prefer a hardtop F-body, but most of the drivers love their t-tops, whereas on here, they are cursed for the most part.
Maybe 4th gens are stiffer than G-bodies, but I've never noticed a flex in the V8 cars.
Anyway, I hear the leak complaint a lot from 3rd gen owners...most 4th gens don't seem to leak much (mine don't, knock on wood).
