There are 3 new later 2nd Gen Diecasts out there is a (yellow 3 spoke & a 5 spoke wheel), you could find them locally
If you can't http://www.milezone.com/ is a good place to get them.
Do a search of "Camaro" for all the ones they have available(approx 30 different, all generations)

wish there was a company that did them with better detail. i'd love to find a 1/24 or 1/18 scale 80 or 81.

Yikess... there seems to be one coming to Europe about $75.00
