Buying Tips for 2000–2002 SEAT Leon Mk1 (1M)

  • ✓Check every electric window carefully because regulator failures are common on older VAG hatchbacks.
  • ✓Test central locking on all doors and the boot; failed lock modules are a regular irritation.
  • ✓On 1.8T and Cupra models, look for honest evidence of sensible tuning and regular servicing rather than bolt-on parts alone.
