1994 C280 m104
Purchased used in 1999 with 14k original miles (still smelled new!)
I'm remembering all this stuff at random.

Rebuilt transmission at around 60k
Replaced shredded serpentine belt (which also caused replacement of fan-clutch) at around 60k
MAF at around 100k
Complete inspection/service at local indy Benz specialist at around 40k
Equivalent of "Service B" at 100k
Engine wiring harness at 150k
Plugs at 150k
Replaced airfilters at random (when visually inspected and found to be needed)
Mobil 1 0w-40 every 15-20k
Water pump at 130k
Everything from the radiator forward (including the radiator itself) replaced at about 110k when I hit a deer at 70mph.
Front pads at 90k
Front rotors at 160k
Rear pads at 160k
Rear flex disc at 150k
Driveshaft center support bearing at 150k

EDIT:
hahahaha, I can't believe I forgot this:
HEAD GASKET , valve cover gasket, intake seals/gaskets, timing cover gasket at 178k

STILL NEEDS:
All O2 sensors, vacuum valve that controls center vents, vacuum connectors in passenger rear door lock, all new sunroof track (glass and motor are fine), MAF, plug wires, shocks, LCA bushings, motor mounts, driver's headlight (cracked in rear housing--causes it to fog up), convenience relay (wiper delay and blinkers work randomly), factory stereo head unit, transmission mount

I speculate I need roughly $10k in parts.

But I'll drive it anyways. Until she catches fire.
