WWII jeeps

My pap (HE'S 88 years old) has been wanting to buy a WWII era jeep.He served in the 91st infantray division and fought at what he refers to as Casino, calls me today and tells me that there's an auction going on around the corner from where we live that has a few jeeps.I am asking that anyone on here that knows anything about these jeeps chime in and give me some info please.We don't want to go in blind, if he does decided to buy one.I would like to give you more info on his time served........but he is very reluctant to open up about it and I can understand why.Thank you Mark
