Is the blue one in the second photo the Opala SS that was discussed when it came out in green? I like the Matchbox Ford Sierras. The RLC cars look really good too. And I see you've found the Laguna Seca with the 2012 body. Apparently there is a variation where they shipped them with a 2010 body and you can easily tell by it having mirrors or not.
That's a negative on the Opala, there's still only the green one afaik. The pic is the 1999 FE of the '70 Chevelle SS. I've been keeping my eye out for the Boss 302 vary; I was able to find a silver one like that.
