Dave's suggestion is probably the best.
From my experience, pristine condition to a seller is typically not even close to reality once viewed personally. Photos don't tend to show off crazing, gel cracks, etc, which are typically no big deal, but I prefer to hear about them ahead of time.
Perhaps find a surveyor
who is willing to look over a boat for an initial assessment to report to you, then if you like the initial report, you can have them do a full survey
before you even see the vessel. I'm sure that would be less expensive than travel.
