I had my clutch replaced at a main dealer, cost no where near 5k, something like £3800 Inc vat. If someone tried to charge me 5k, I'd have laughed at them thinking they were joking. Why anyone has been told that a clutch is that expensive is strange. I had an experience at a main dealer where I was told a 30,000 service was £4000 + vat, when I later spoke to the man in charge I was told the true price of about £1800 and he apologised that I had been mislead. so don't believe everything your told.
Oh I'm not stressed, just amused at this thread. It's funny to read people who have never owned a car making wild an inaccurate comments. Carry on please, perhaps you could talk about the costs of the brake disks, or petrol cap.
