Things to look for in a 4th gen

[1980 TA]

I'm toying with the idea of purchasing a 4th gen. Any general things to look for or avoid would be helpful.

I like the looks of the 95-97 WS6 cars but would imagine anything with an LS might be better.

I have T Tops in my second gen and love them during good weather. How are the 4th gen T Top cars? How's the headroom in the non T Top cars. I'm 6'2 and rub my head in a 2nd gen hard top car. Don't want to have to fight that in a 4th gen.
