My Starlet had over 105k miles and would still be running now if it wasn't for the radiator failing. It's for sale if you're interested, it now has a new engine with 67k miles on it, new radiator, and I've done the clutch, cam belt, alternator belt, oil & filter, etc... and it will have 12 months MOT on it soon once the rear brakes are done. If you end up buying that one on ebay don't worry about the miles, just make sure it's got good service history and it will be fine.
