nothing wrong with high miles or auctions just make sure its got plenty of servive history .my sons mondeo tdci has 260,000miles on it and still purring he just got rid of his 07 plate lexus with 190,000miles but he has a full service every 12 weeks because of the miles he drives . if your buying just the one car for yourself and your carefull and look hard you should be ok buying out of an auction .but always remember [caveat emptor] buyer beware and be prepared to be bit .lol.
