With all respect to Jay Zed, the advise you got was not from the “purists” in our group. Only one of the responders was a period correct guy. All the rest are/were Hotrod guys. The truck is only worth about 1/4 of the asking price at best no matter how many miles Gateway says the owner drove it.
There's many forms of purists. In this case it was a euphemism; I was trying to avoid the term "sanctimonious snobs." If you think I'm wrong, then please point out one thread where they have actually had a positive response to someone's buying inquiry instead of shooting down their dreams. And I got that 4000 miles figure, not from Gateway, but off the truck's odometer.
