There is a '95 S320 for sale at the local MB dealership here that is in beautiful condition. It has about 100K miles and they want $10K or so for it. I would say that the Mercedes dealer would probably be a safe bet for finding good condition cars. I'm sure they get a lot of trade-ins, and the cars they sell there would have passed some sort of inspection. If a car is in truely bad shape, it is doubtful an MB dealer would attempt to sell it. Also check Lexus, BMW, Audi, and other high-end dealerships- they frequently get MB trade-ins, and they also would not offer a car for sale if it is not in good condition overall. I bought my E320 at a Lexus dealership, where it was a trade-in. It was a one-owner car, and in beautiful condition for the age and mileage. Don't be discouraged, the W140 is a car that is unique enough that there should be many owners who took very good care of them.
