Buying Tips for 2014 SEAT Ibiza Mk4 (6J)

  • Check the rear footwells for dampness (door seal failure).
  • Avoid the 1.4 TSI "Twincharger" (found in the Cupra) unless it has a meticulous service history, as they are prone to piston failure.
  • The 1.2 TSI (8-valve) pre-2014 has a weak timing chain; listen for rattles.
