[Number 3]

Look, I understand the desire. I had them on cars I've owned and driven.

As Angrybird pointed out if it were easy to do somebody would be doing it. The Jeep does, but it is effectively a convertible. You could do a 2 piece but that attached to itself would not be robust for leaks, windnoise, and of course structural rigidity.

I'm not really sure how anyone keeps coming back with "but space age materials......".

I've done this stuff, guys. I've run many FMVSS 216 tests in my career and I've had to create designs to meet that specification.

IT.........AIN'T........SIMPLE and there are no "space age materials" that make it any easier AND cost effective.

If I had a marker board I'd draw you guys a picture and then maybe you would understand why it's really, really hard to do.

But cars that had T-tops

Nissan 300Z
Ford Mustang
Olds Cutlass
Buick Regal
Pontiac Grand Prix
Chevrolet Monte Carlo
Chevrolet Corvette
Chevrolet Camaro
Pontiac Firebird
Dodge Magnum
Dodge Aspen

More?

So simply ask, with a long history of this feature...................why is there nothing in production that is technically a T-top? Many Targas, many convertibles, many sun/moon roofs. No T-tops. Why is that? Would be a huge market differentiator wouldn't it? But none. Ford used to have it on the Mustang but not for many years. Why, oh why would you expect it to be possible on the Camaro?

So it could happen. I believe it is feasible. But you wouldn't like the result.
