9: Interior
Another thing that potential classic car owners overlook is the interiors. These interiors are often very old and the materials are no longer in use. Vinyl seating for example is not used at all anymore by any major automaker. But if you are getting into an older vehicle the chances are that it has vinyl seating. You’ll want to examine this and go over things to see what you might need to do to upgrade it.

Yes, keeping the original seating is important, but it can also be a very costly investment. You’ll notice that a lot of classic car owners are upgrading to modern interiors, and there is a reason for that. The cost of upkeep is much lower and the materials will last a whole lot longer in the grand scheme of things.
