Scott's post showed up while I was writing my response; I don't want to leave you without response. Yeah, I think you're right. The car is too big. I'll play with it some more, although I did play with it for quite a while when I was building the scene. Much smaller and it looks way too small. It might be a factor of the 35mm lens I'm shooting the scene through, but I'll see what I can do to get it to work right.... Thanks for the comments and the calculation!
