and it seemed clear on the forn that it had to be signed by someone at the dealership to confirm the mileage reading; I happened to go near a dealer on the way to pick up my youngest daughter from college, and they seemed to agree that someone in a responsible position at the dealership had to sign it, so the salesman went to fetch the sales manager and when the salesman verified that he had checked the odometer and it read 313,000 plus, the manager signed it. The salesman was enthusiastic, but the manager seemed a little annoyed.

I believe that you do not need to be the original owner to get the grill badge, but you do have to have made that many miles in Mercedes cars (cumulative) to get the lapel pin. This '85 300TD is the first M-B I have actually owned, and I've barely got 12,000 miles since I got it, so I only applied for a grill badge.
