He has no come back legally as it was a private Sale
and "Sold as seen".
For all you know he may have been raggin the arse out of it big time therefore what does he expect.
If he wanted a warranty and consumer rights he should have gone to a car dealership and bought a car through them and then he would have legal rights and a warranty but also would have paid allot more for the priveledge.
He carnt expect to pay private Sale
prices but recieve all the benefits from a Dealership Sale
Whats happened to the car now and whats he said about in Andy ?
