Servicing cost advice
 

Having some work done on my car, providing all parts and fluids myself. I've been a bit unpleasantly surprised by the price I've been given. Any opinions on what ballpark the following should be costing (just labour)?

* Cambelt replacement, including pulleys & tensioner
* Replace radiator with new
* Gearbox & diff oil change
* Engine oil change
* Brake fluid change
* Spark plugs change

I brought all Motul Oils and fluids plus a full cambelt kit with the HKS Kevlar race belt for £600 for my spec c then paid I think £500 to have it all done :)
