Reliability and running costs very bad C350
I have a 2008 C350 that has currently done 100 000 miles/160 000km and in that period so many expensive things have gone wrong. I have converted to dollars to make is easier. I have it serviced at the Mercedes dealership on time every time where I bought the car, second hand from so it wasnt like from a dodgy dealer somewhere.
Here is a list of whats gone wrong
Anyone else have these sorts of issues or care to comment?

I repaired the driver side's headrest myself as this instruction. It wouldn't be like OEM but that is okay and I didn't consider it as an issue.

Other than general maintenance, my 08 C300 has been pretty reliable @120,000km.
- replaced brake booster -> covered under warranty
- replaced pass headlight assembly -> covered under warranty
- replaced upper idler pulley -> covered under warranty
- replaced lower idler pulley and belt -> diy
- replaced thermostat -> diy
- replaced HVAC blower motor -> diy
- replaced oil separator -> diy
- replaced power steering pump with reservoir -> diy
- replaced front seat bottom cushion -> diy
All of items are minor...

2011 C300. I have 150,000 miles on my car and spent $4,600 in services/repairs. Maintained by the book.
This includes brakes and a windshield replacement, two transmission services as the most expensive repairs.
The only real repairs I’ve really done that isn’t a maintenance item is below:
Thermostat $120
Transmission Mount $50
Front and Rear flex discs $150
Two minor leaks at back of engine, plastic cap and cover (forgot the name) $80
Front left and right end stabilizer end links $60
Left bank Cylinder head (replaced under warranty $0).
AC center vent (replaced under warranty $0)
Cup holder with arm rest (replaced under warranty $0)
Car drives like new, I am on my 4th set of tires.
Bone dry, not a single leak. Everything works.
