It took me a few minutes to get them straightened out when I bought my '71 250 with the straight numeric VIN. I didn't have that problem a few years earlier with my '77 240D. They never got the impression I was driving an R107 in either case. The companies are gear toward newer cars, since that's what they see most often. A hiccup here and there with an old car is to be expected. Grade them on how quickly and well they can get their ducks in a row.
