  • ✓Check the rear leaf spring mounting points and front strut towers for corrosion.
  • ✓The A-series engine (1.2L) is virtually indestructible; if it runs poorly, it's usually just a dirty carburetor.
  • ✓Verify that all original trim is present, as finding replacement dashboards or door cards in the UK is very difficult.
