Sorry if im starting to sound like a fcccuking arssse, but i am a trader, whilst i understand people and what they want, and that they should buy what they want, are happy with and is exactly what they "think" it is, it is a bit unfair to flair off at a trader with the wrong information, as is to try for a refund because you think you could have bought cheaper.
This will be taken both ways, but if he said the car was 400 quid, no one would say take it back, they would say get a key from timpsons. Its a matter of opinion and obviously the buyer was happy with the price, so in the eyes of the buyer the issue is the key, not the price!!!!
And on the auctions, ill admit bargains can be had as the punto legend Dave suggests, but there are some bad ones and at least with a trade sale you do have the chance to inspect and conduct checks. I wouldnt advise a new buyer to go to the auctions in my opinion. Although for those with good knowledge then they can throw up some bargains!!!!
