Low mileage 2009. What service is necessary?

Just purchased a 2009 clk 350 coupe with 18379 miles. Have been working to bring cosmetics/tires to new condition. Car drives great - no problems apparent. Only had a couple of oil changes (maybe 1 b service) in its 13 years. What do i need to have serviced because of age? Any help will be greatly appreciated. Thanks.

Low mileage coupe, nice.

Oil - done. flush the brakes and coolant.

How do the tires look?

All of it. Go through the entire vehicle.

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

Thanks for comments.

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.

Replace the coolant.

Don’t test the fluids, replace them.

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.

Indy appointment today for my new to me 2009 CLK 350. Car now has 19,560 miles on it. Thorough inspection: Brake fluid shows no moisture, Coolant is as new, transmission oil is as new. Recommended Air filters, Cabin Filter, A/C recharge - no other problems found. Advised that only - if I needed piece of mind - they would flush/replace Transmission Fluid. Indicated that the old would look/test exactly the same.

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.
