new member that let the horse out of the barn

You are looking for things to watch out for in buying a w210 after the fact.Cross your fingers on an ebay purchase is the first thing to look out for,the other items no worries,cept the window regulator and that might never happen.
Did you get a warranty?Did you get a professional PPI?
How much did you pay?Was it a used car dealer?

03 was the last model year for the w210 wagon and while most things were worked out ,it does no good if you did not inspect,inspect,inspect.
