Sorry for note responding sooner. I had to go out of town for work and didn't have internet access. Thank you for all the nice comments.
re: scale. The car has 1/48 scale printed on the bottom, but I suspect the scale is off a little. It looks a little big compared to some of my minis, but overall it seems to work.
re: model v. diecast. The car is diecast and I found it at a local drugstore, Rite Aid I think. This is the one and only Caramo I have seen in this scale.
re: lights. The headlights do not light up. They are just painted really well... and not by me. ; )
Thanks again. I hope to post some more pictures of vehicles soon. Cheers.
