I think the true rock stars in thei category are those like Harry Sheets, John Bizal, the guys at Kaiser Willys, Darryl Bensinger, and Ron Fitzpatric who travel worldwide to get our parts for us.
As far as individual jeep owners go Lonnie aka CheapJeep shows up at the reunions with a tractor trailer full of jeeps, all of which are amazing examples, no plain jane ones at all.
I travel coast to coast, and have jeep parts in my collection from New Hampshire, Florida, California, and Washington State. I do travel for a living so it isn't like I took off to parts far away simply to get a jeep, although I have purchased two trailers on the road to drag home what I found.
One of these days I will get off the road long enough to finish a jeep or two. Then I am going to have to start selling off the surplus, of which there is plenty. My method has always been not to buy individual parts, rather choosing parts jeeps and aborted projects to get parts from. I have a Surrey jeep and things like bumpers and hubcaps, always huge money on Ebay, came with jeeps attached.
For me the chase is the adventure, until I get to go in my own jeep on a Colorado trail ride.
