Darius,

I purchased the car in 1998 with 75,000mi. I brought it to a MB dealer for 60,000mi service which they recommended since there was no prior maintenance record.

I am looking at the 60,000 service invoice and do not see O2 sensor being replaced. Is that a special item or should that have been done automatically?

The only major work since is a new water pump in Feb 2000.

The car is running fine, I get anywhere from 17-22MPG mixed highway and city driving. Oil loss is about a quart every 3000mi.

If you need more specific info let me know.

Thx
Michael Chan
