It seems to be that it’s borderline insanity to not have that car put up on a lift and have the undercarriage inspected before handing over any money.
Maybe the reason that the car is for sale at a good price is because the seller knows something that all of us, including the potential buyer, do not; as in rusted brake lines, rotted subframes, etc, which may have caused the seller to balk or failure of the car to pass a PA state inspection.
I’m not pyschic so I don’t know; just saying that prudence is better used before the fact rather than after.
Check the build tag on the door jam and odds are one would find that car is 7 years old, not 6.
Judging from some of the Rust Belt cars that end up here in OK that’s more than enough time for rust to become an issue.
