The last time I visited a dealer to see a non-running MB (Dean Team in Kirkwood, btw), they were sending it to a M-B shop to fix some leaks. They wanted about $15K for the car, and I was quite interested. I gave them my phone number and they assured me that they would call me when it was drivable.

I didn't hear from them for a few days, and when I called them about it, they told me that they already sold it to someone else.

I imagine that they figured that since I saw it spewing diesel, that I wouldn't pay an acceptable price. Instead, they're off my list of people with whom I will deal. In fact, I bought a brand-new Jetta TDI from a competitor and didn't even check their price. I didn't care.
