I see how easily it starts, how it shifts, what body work needs to be done, is there obviously excessive blowby, are fluid levels in spec, check the interior and look in the trunk and floor for rust. Does heat & AC work?

Next plan on $500-$1,000 in parts and estimate install pita for what I don't see. Then ask the gut if I'd be happy with the car for that price. If AC not working, pass or add $1,000 to my expected cost.

Alternatively, ask the owner to drive 2 hrs at hwy speeds to meet you saying you'll buy with cash if it is as described. Few will drive an unreliable car that far to try to unload it. Few will drive that far and lie to you. Some will drive because they are uneducated and don't know what they have.
