thats simply not true. if i brought a £100 banger from a dealer, even if they didnt explicitly say 'its disposable', if the hg went after 5 months i wouldnt expect a penny back. if the fault was not present when the car was sold, they only have to warentee it for as long as they say. if you want longer cover, buy a longer warentee. simple as that. the law is VERY different for new products (where you could legitamately claim) to old products.
