Congratulation James!
May the third 100,000 kilometers be even better! In the old days Mercedes would send you a nice certificate, gold lapel pin and a 3" diameter porceline grille badge for each 100,000 kilometers. Now days you have to wait until 250,000 kilometers for a smaller version badge.
The early 3" diameter grille badges show up on ebay from time to time. They are collector's items these days and are fairly valuable. The 100,000 kilometer badge was blue, the 200,00 was red and the 1,000,000 was gold!
