someone on here had a Skyhawk with the acrylic(see through or glass roof ) if you want to call it that. I'll try to find it, it was a couple years back.
dr frankenstein is his sreen name and he just sent me a pm saying he still has it. I don't have the pics anymore but the roof is still intact. It needs work but have you ever seen one with the glass roof option? Not likely, very rare and I think would be awesome.
