Now when this dealership was under old management, THEY SUCKED. I still see some of the same people there today as before, so it's likely not much has changed. It's also very possible that the car isn't even there anymore. Sort of a classic sleazy car dealership "come on" trick.
The car's VIN is listed, WDBCA24DXKA468770. I ran a Carfax on my 420 SEL about a month ago and was thoroughly disappointed (their records only went back to 1991, whereas M-B's went back to the day it was delivered in October of 1987). I don't qualify for another Carfax refund, otherwise I'd run a check (they list 12 records as available).
