Hi 300SDude interesting car not real sure about value as the factory never made 1 in a Deisel. And that model was when the SL was a Sports Light so fuel usage was about the same as your 300SD had the pleasure of driving one years ago. From Canberra to Wollongong through the Kangaroo Valley . Then back to Canberra via Illawara highway/Hume . On less than a tank of fuel about 600km all up .Loved it thanks to my older brother when he was a Lexus salesman
