Gavin - It's true that Mercedes Colorado beige seems to incorporate a whole spectrum of nuances depending on the life the vehicle has led, which may lead to confusion. In the case of my w123 (sadly sold last year), it was a sorry, flat, milky colour when I got it and only much vigorous polishing bought out the orange hue. In fact, one of the reasons I sold it (apart from the acquisition of the 280SE) was the alarming rate at which the paint lost it's shine - keeping it looking nice was like painting the Forth Bridge! I suspect it had had a cellulose re-spray at some time in it's life.
Hi Floyd, yes, that is the original interior and the seats are as they left the factory - a tribute to M.B. robustness! I'm wishing I had kept hold of it now....
