If its true that the 6th gen is going to have some 2nd gen styling cues, and since there are some people that don't think that its a Camaro unless it has T-tops. Then how about a glass top? Similar to what Ford currently offers on the Mustang, but with a dark center stripe to simulate T-tops?
GM already has experience with these kinds of roofs on Opel and Vauxhalls in Europe. Traditional T-tops, although cool, would really be a compromise with todays increasing concerns about impact worthiness, not to mention where to store them.
