All Warlord jeeps are being resculpted, so don't use their store as a guide. I have the Chevys, which are very nice, but need some extra guns for 'proper' load outs. Offensive minis do reasonable looking Chevys with guns. I'm not keen on minis from Company B, based on other models of theirs that I have. I have a Perry truck with Bofors and it's a decent kit, but not quite up to Warlord standard IMHO. Dixons do some good metal jeeps, if you prefer the weight, Rubicon get good press apart from the heads, which people say need replacing.
Bear in mind these are all 1/56 scale-you may find other model kits in 1/48 if you prefer it?
