Check for rusty brake discs, flat-spotted tyres, condensation damage to the exhaust system and moisture in brake fluid. A lot depends on how old it was when first registered, so whether it sat there through last winter as well as this winter. Check the DOT dates on the tyre -. the first two figures are the week of the year they were made while the second two figures are the year of the decade they were made. But if it's £5k - £6k may be worth buying. A new Picanto or i10 will be closer to £10k .
