Well lets put it this way. My leon is the last SEAT I think I'll ever buy. Problems so far:

1. They didnt put enough oil in the gear box so it kept coming out of gear as it wouldnt go into gear properly.
2. A the main pipe of the master cylinder on the clutch burst leaving me without a clutch.
3. The entire rear half of the fuel system has been replaced as I couldnt get any fuel into the car. Replaced the air release valve and told me it was fixed. It wasnt. I sent it back and the service manager (who has since left the dealership) told me it probably wouldnt be a warranty job as he thought someone had syphoned out fuel and left a rag down there. When i pointed out they would have had to break the cap off to do it he said they wouldnt etc etc. I was then accused of syphoning out my own fuel. I did get the work done ventually.
4. The car rattles and the tracking keeps going. The last time I had the tracking done I had the wheels re-balanced, etc and 1 week later it went back to how it was before.
5. Door trim has fallen off.

Whilst I still like the car and dont like to have a go about it I wouldnt have another. My local dealership is better now that the kn0b jockey (Former service manager) has left but i still dont trust them.
