Low mileage 2009. What service is necessary?
tires
brakes
engine oil, engine air and cabin filters
transmssion oil
axle and transfer case oils if 4matic
brake fluid
Thorough cleaning of underhood and door apertures/sills. This turns up maintenance jobs.
replace battery(ies): main, aux and key fob
Replaced tires, car cleaned/polished/ceramic coated. To be thoroughly inspected by Mercedes indy. Plan to proceed as he recommends. Only service in 13 years: A service and 2 oil changes. 1 right before I got it. Indy says can test fluids - may not have to replace all. Will let you know what he recommends in a couple of weeks - he is busy.
Car drives great.
About 5 years ago I was in the same boat. Bought a very low mileage 2009 CLK Coupe. Even had a warranty with it for 1 year lol. Not as low mileage as yours but since it was used by a couple who kept it at their summer home I knew it sat a lot. Even if the mileage is low and is hardly driven you need to still change the fluids. My recommendation is to just change all the fluids if you have no record of anything. Piece of mind.
It looks like I can safely wait until the next service to replace Trans Fluid and Brake Fluid. I note that the Maintenance Manual says the coolant is good to 15 years or 150,000 miles.
YMMV.
