Dumb question or not, I keep seeing posts referring to slick tops, I'm guessing that's a car with out T tops (TT). Googled it, but just found a lot of other forum posts without much info.

 

Slicktop= normal roof, no T-tops! TT= Twin turbo!

 

This is my 86 slick top

 

Here is my 1985 Slicktop.

 

Thanks for the pics, Ill add them to my desktop collection. She looks in great shape, very clean, looks like you replaced the nose at some point, accident ?

Cheers

 

Slick top = hard top. That is, a solid metal roof.
TT = twin turbo found on z32s, not z31s. Some z31s have a single turbo.
NA = Normal aspiration (meaning there’s no turbo)
T-tops = T-bar roof = roof hatches. They were an extra cost option on z31s but most z31s exported here came with T-tops.
