Hudson,
Man I have been in your shoes! There might still be some kind of light at the end of the tunnel. Did you by the car from an individual or a dealer? Contact me off-line and lets talk! I live in the mid-cities and have two 300SD's and two 300Ds. There are a few really good shops around here so I could give you some advice.
