There are a number of us on this forum that have bought bikes across the country and have asked another long term member on this forum to go look at the bike for us. A couple of years ago I bought a 13 CVO Ultra Classic w/matching Bushtec trailer after I asked Chip & Nancy to drive up to W.Va. from N.C. Best deal I ever made! Well, next to the truck and 5th wheel trailer that I bought this week.
Andy bought a bike back east (don't remember the state) and asked a member of this forum that we'd never met, to go look at it. He bought the bike and then had another member of this forum store the bike for a couple of months until we could get out to the east coast.
Others will probably pipe in here about their experiences but I've seen it happen a number of times on this forum. So far, I've not read of a bad experience.
