here is a pic of my mom's vette.
This is the only top down view I have of the car (had to climb a tree to get it

) and the reflections don't let you see in but it is a plastic targa top - not t-tops (she also has a seperatel color keyed top as well). Outside (in person) it lookes tinted gray. From the inside looking out it has sort of a terquoise tint to it.
Never seen it on a supra before but if your car is black, you could limo tint the roof. It shouldn't be illegal as it is not required for visibility. right?
Might look nice!
*edit: this pic was taken a while back. No wheels or lights on my car yet. (no mods either! smic FTL!

). What a difference looking back! I had doubts during the purchaseing phases but damn I don't regret a thing looking @ this old pic now! ...except the wheels are a flippin bitch to cleen and keep cleen!
