Hi,

I bought a car 8 months ago from a large dealership and have had to take it in today because the engine was misfiring slightly.

They have just told me that this is due to one of the spark plugs being heavily worn. They then go on to tell me that my brake pads need replacing as they are 90% worn....

My question is... They told me they do a 120+ point car check on every vehicle before they sell it bla bla bla... So would they not have checked the brake pads and the spark plugs or have I worn these things out in a mere 6k miles since getting the car?

The car is a Vauxhall Corsa Sxi 2006 1.4ltr

They are charging me £230 for the diagnostic and spark plug change and £180 for the brake pads. :(

I have mechanical warranty with the garage but this does not cover either of these things apparently.
