There is a guy in Phoenix I periferially know who has probably 100+ WW 2 jeeps in every model you can name. What he is willing to part with I can't say. At one point I was thinking of getting a USMC mechanical mule from him for $5500 including an extra new in crate engine and a spare set of tires for it (to use as a 'super' ATV for construction).
I met this guy doing some electrical work for him.
