I bought a Seat Leon from Your Car Mar Menor. It came with a 12 month warranty covering engine and gearbox. It developed a problem with the timing chain which started to rattle on start up but only now and again. They booked it in and changed the whole timing belt assembly (not just tensioners) without any problems at all ( 5 hours labour and parts covered). Provided me with a courtesy car while it was being repaired too.The car came fully taxed and as the ITV only had 3 months left I was asked to drop it round nearer to the renewal date and they would take it in for a new ITV at no cost.
Absolutely brilliant service by Andy and Amanda and nothing seems too much trouble. Check out the website.
