I was just watching a chevrolet truck commercial and about halfway thru the commercial, they was showing a some older chevy trucks and right behind the truck is what appeared to be a thunderbolt in the background. It was very easy to see but i just caught a brief glimpse of it. Someone with a fast computer, (faster than my dial-up) could probably find it on youtube and post it. Seems like one of the first trucks in the video is a green 60's-ish chevy stepside.
