All the above untouched, as per records and my usage started 6/'13.
One GP failed before I bought the car as per records.
Ribbed V-Belt changed as per records.
Numerous brake pads and rotors changed before buying - this is normal. These cars eat both pads and rotors X 2 what my other MBs have.

Under my 6K driving since buying:
Plenum gasket needed R & Red - it was leaking oil.

Elected to install (6) new glow plugs.

Fuel tank door locking pin device needed R & Red.

Blower motor replaced. Original was ticking at low RPM, and bothersome.

I changed out both engine mounts myself - one was leaking - spewing brownish hydraulic liquid. The pair of engine mounts were just over $300.00 - even @ MBCA Member pricing.

Have had fuel filter/ oil/oil filter replaced.

If anyone is buying one of these thinking they'll never need to spend time and money (at times a lot of both!) keeping them up-to-snuff, I think they're going to be very disappointed.
