I'm not a fan of convertables so I'm a little bias here, but the rear of the vehicle just doesnt look right. I've seen the Corvette convertables and they look really good, little difference to the coupe, but thats just not a Camaro to me. I'm reminded of the 4th gen Converts which had the same problem.
I might get flammed for this, but to me, a Camaro is a coupe and a Vette is a convertable.
But, if its going to be done, hide the antiena in the windshield pillar, and work the 3rd light into the spoiler. It would look alot better.
Sorry for the spelling errors.
