BUY!!
If I had to describe a Mercedes-Benz to someone, who had no idea of what one is, a picture of the W116, is what I would use! They are Classic, and get better to the eye, as they age.
I am thinking along the same lines, of whether, or when, should I pull the trigger. A Diesel, 4.5 or 6.9 even. Try to buy the nicest one you can find, it will be cheaper in the long run....
