Actually, if he sells it privately, there is very little scope for "comeback" ...
... provided they don't make any claims about the vehicle that you can't be sure about.
Don't say "it's in great mechanical condition".
Say "it's never let us down, but we have no mechanical knowledge".
That sort of thing.
Advise any buyer to come and inspect the vehicle, and to bring some sort of "expert" with them, and to make up thier own mind about it.
