Stalling at junctions, Hesitation when accelerating, Strong smell of fuel

Buying Tips for 1979 Datsun Sunny (B110/B210/B310)

  • ✓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.
  • ✓Early 120Y (B210) models are now highly collectible for their quirky styling; check the "fastback" roof for corrosion around the rear window.
  • ✓Simple mechanicals make these excellent cars for DIY owners.
