Can you solve a mystery for our family? Our elderly aunt and uncle, run a 1983 Mercedes W123 estate, 300 TD, auto, with air con. The car is built like a tank, and is most reliable and solid. My uncle and aunt, will not part with the car. Just recently they have had a plethora of all types of dealers with low loaders who want to buy the car for as much as £1,200. Just why are these people interested in elderly Mercedes? The dealers that knocked at the door all had W123 Mercedes on the backs of their low loaders that they had obviously obtained from various sources. As you know these types of dealers are as tight as a drum. Do they have a lucrative market for W123 Mercedes?
