In Pennsylvania, if I sell a used vehicle to somebody (privately), and
have them sign something such as:

This vehicle, a (vehicle name/VIN #), is being sold as-is, where is,
and without any expressed or implied warranty, and without regard to
any fitness for a particular purpose.

Would I have any problems if they came back demanding their money back
if they found any problems with the automobile?

I take it the Pennsylvania Lemon Law only applies to new vehicles sold by a dealer?

I've looked everywhere but want to see if anybody has anything I've missed.

Thanks!
