Had an ibiza, very badly built compared to Polo . Dodgy electics , pedal mounting buckled behind the clutch because of build and bad welds , banjaxed clutch too, loads of grief geting them fixed under warranty . Radio banjaxed , same grief .
Thought dealers for seat were weak and under resourced compared to VW for servicing , small garages, bad parts stock , lots of 'have to get that in ' excuses during services .
Got golf instead of leon when I upgraded , very happy with it. Will not go back to Seat for crappier build quality even though they handle well on the road.
