I am not sure what they do exactly on a 2 year service, it should say somewhere in the manuals or you could ask the dealer for detailed information on what they are doing for this figure. It may also be worth ringing round a few other dealers to see what they are charging, I have read about a large disparity in delaer prices for servicing.Final note under current block excemption rules you don't have to have the service carried out by a Nissan dealer, any VAT registered garage can do it, they just have to use parts of the same quality. One word of caution on the latter if a car is not serviced by the dealer any goodwill gestures you might get from Nissan will be gone and you will have to keep a record of exactly what parts were used in the event of a warranty claim.
