There is a resin kit, I think it is from Verlindon and is about $100. I wish there were more out there because I really like the Cadillac Gage armored cars (V-100, V-150, V-200, V-300, V-600, Commando Scout and Ranger) but nobody seems to make kits of them and I don't like them enough to spend that kind of money for one.
Here is a link showing the kit
