I am not a big Corvette fan, but I missed out on this one last time, so I'll get one.
The '61 Ford builds up nicely although it has a 4 door interior. If the hood is opened up, the '63 Galaxie chassis, engine, firewall, ect. will yield a nice kit. I'll definitely grab a few.
The Olds, well, I have a few so I'll probably skip it.
