How much is cambelt change for a peugeot 206?

I have a peugeot 206 GTI 2.0, the car is 8 year's old and has done around 62,000. I'm a little worried as not sure if it has ever had a cambelt change, so decided to et one done. I've been quoted 拢240.00 to over 拢300.00, what would be a good price?|||Your local dealer will have a discounted fitted price for cars over 3 years old. Your belt is due at 80000 miles but doesnt hurt to change it early.
