Parts ??? I don't think that would be a problem .Keep in kind, between 50's-60"s evey year huge major changes for American brands .
For instance: '53 Chevy Bel Air is totally different to '54 Bel Air

 

Yeah but insurance on say a 2008 toyota pickup truck are way more expensive than they will be in 2015 as there will be many aftermarket companies that have parts for the cars...when more parts are readily available the prices on insurance go down...know what I'm saying?

Supply and demand concept...
