Reebs,
An excellent idea that I'm sure will catch on.
Whilst not mechanically minded I would gladly go to have a look at any vehicle close-ish on behalf of a member and would definitely ask around if I was the prospective buyer.
When I decided on a 75 Tourer the one I got was the 8th I had looked at.
SWMBO accompanied me on each trip. The trips back were not as nice as the ones there each time!!!
I did over 750 miles before finding the one I wanted
