Yeah, money and space helps!  But if you're willing to do some work on your own as well as spend some time and money, you can find a fixer-upper cheap.  A lot of old army jeeps, for an example, are found in barns.  Many can be bought surplus, but those usually need some work too.
Haha, Steel Soldiers...  There's a picture of my M37 up there that someone else took the day I drove it out of Fort Drum!  I like that site.
Is there a way to upload my pictures onto the forums somewhere?
