I did my 100k service 2 months ago and costs came to just under 1k.
Gates timing belt, genuine Nissan water pump, tensioner bearings, seals = $425
Engine oil, filters, fuel filters, rad coolant, fluid change + complete safety check + labour for the whole job = $500
Dropped my car off to my mechanic in the morning and was completed in the afternoon. This is a mechanic I use all the time and sometimes I don't really question the prices as I know they always get it right the first time and they're not here to rip me off as I've used them for almost 10 years.
