Yeah, that would be great if I could find one!! LOL Last time I saw one was right before Christmas last year at Wally-World... They had 1/6 scale R/C cars of the concept. I went back to get one and they were no where to be found! I haven't seen them since, even online there doesn't seem to be any on ebay or anything.Not been published, but there are a few posts around from SS that say something like 2 inches taller and 1 inch thinner than the concept. And some people have compared the pre-pro shots with the concept, and decided that the door and windshield is different.
I would just go off the many die-casts of the concept. You know, they make a Camaro Concept R/C car.
