Why won't he state who the trader was..
1. Is the seller in the wrong for selling a car with a known fault, hence is embarrassed it's all come back on him.
2. Was his posts genuine and jut an enquiry to PAS problems which wern't too bad. Maybe the trader is on here an saw his posts and then knew he could say its a problem?!
Either way... Wouldn't of paid if you knew nothing was wrong. Or if you did know, fix it before sale or state about the problem in the add or at the viewing!
Either way, like people have said, why post up for advice? Family issues or not, blocking his number after telling him you want writing from a solicitor solves the problem totally as you would of never got any writing!
