I have a 2013 C350, 64,300 km. It is due for an A8 service in 30 days. Canadian vehicle. Service manager says it needs service items 1&3 for ~$450 (A-service - oil and filter, etc.) , 10 for $40.00 (Sunroof lube), and item 20 (trans service) for $800. Costs are $Cdn. While I trust the service manager (known him since the 80s from Volvo, Acura and MB dealerships), and the dealership has been good to me over the years, I'm trying to get a sounding on these costs as it seems like a lot for service items - Are these excessive? Is it worth seeking out an indy shop or is it worth staying with the dealer?

Any comments, opinions are welcome.

 

I would find a good shop that specialize in Mercedes and or European cars.
For my 2013 C250 I've done all these myself. I use Castrol Edge 0W-40 European formula which is approx $29.00 for a 5 qts jug, I need little less than 6 qts, oil filter is about $15.00.

Oil change should not cost more than $100-$150 US and tranny service should be around $450 at an Indy shop.
