Buying Tips for 2012 Maserati GranTurismo / GranCabrio

  • ✓Prioritize 2011+ models where the variator issues were largely solved at the factory
  • ✓Inspect the undertray; it is low and frequently damaged on UK speed bumps
  • ✓Check the TPMS (Tyre Pressure Monitoring System) sensors; the batteries die after 6-8 years
  • ✓Look for wear on the driver's seat bolster; the leather is soft and wears easily
