Is the dealer right?

Had a follow up phone call after my service and was told that the technician recommended cam belt change. I pointed out that they had replaced the cam belt 12 months ago at 4 years old. "Oh yes looking at your records I see that now" says the service person. I pointed out that they had quoted £230 to replace rear discs and pads but that Skoda National Pricing participating dealers would do it for £189 and he said it wouldn't be a problem to match that price.

Must remember to always question a price/quote.
