There are loads of old cars with hundreds of thousands of miles happily still running. I drive one myself. Older VW, Mercs and Toyotas in particular will run to intergalactic mileage, Peugeots will too if cared for despite the reputation. Mine still doesn't burn oil after 200,000.
Generally speaking, anything that wasn't built by BL/Rover or Renault will last the course.
I never understand why buyers are scared of high mileage cars. Someone covering a lot of miles will usually maintain their car well and most of those miles will have been long journeys on main roads which stress a car a lot less. I'd be way more suspicious of buying a ten year old Micra or Fiesta that had 20,000 on the clock which probably spent it's life been driven around town or on short stop-start journeys and serviced every 3 or 4 years whether it needed it or not than of a ten year old Golf with 250,000 on the clock which was driven and maintained properly.
