I was just reading the current issue of "The Star" the Mercedes Club magazine. They featured a 95 E Cabrio, the body style was available in 93,94,95 and about 6,000 made it to the US. The origional purchase price was about $84,000. This fellow paid $23,500, and it was in great condition with 41K miles a year ago. I would smack the person who told you $5k upside the head. These cars are demanding a premium since it is a four seat convertible. I would hold it, dont abuse it, and find an origional radio for it, the purists will pay top dollar.
