Hello folks, New to Corvettes and New to this forum.
I'm a die hard 1/18 diecast collector and I bought something the other day that I can't get an information on. It's AutoArt 1/18 2006 Indianapolis Festival car in blue. I have a certificate that says 1/6000, but seems like nobody in my diecast groups even knew this car existed,
and we have quite a few Corvette collectors. (They know of this car only in 1/24 scale Franklin Mint) I seriously doubt there are 6000 of these around, (I think they used the 1/6000 blue convertible as a base to this) and does anyone have any information on this diecast? Google basically shows next to nothing. Thanks in advance!
