Given the description, this car is worth approimately $2,500-$4,000. The killer here is the previous presence of rust, vaccum leak, and oil consumption. To the right buyer, it very well may fetch slightly over $4,000. However, given the market you are in (I am originally from Iowa) the price trends slightly downward due to demand. I have found that diesel Mercedes seem to be most in demand in the Southeastern part of the US with prices trending slightly higher.

I would recommend some pricing research on cars.com and autotrader.com.

Anyway, best of luck and I hope you find good buyer.
