Yes, I think so. You can get someone from the AA (RAC) to check that all is well with a car - not sure how much this costs, but it may be worth it.
I know of people who have bought good cars at auctions, and not spent too much money. Cars than have been owned by the police, MOD (etc) are sold at these places. Yes they can have high mileage, but have will have been well maintained.
PS - A few years back, I bought a old Volvo from a place in London. It got 40 miles up the M1, and then a oil plug (or something) went - blue smoke everywhere - RAC took it home, and I then scrapped it. London car dealers
