Your 320 has sufficient miles to wear the first badge. Application for the mileage award can be obtained from MBUSA by dialing 1-800-FOR-MERC. They'll send out an application, you fill out same and get it signed off at the dealer (in most cases). The dealer will probably not even know what you're talking about, they'll just want to sell you a new car because your's is soooooo old. Eventually someone will sign off and you send the form back to MBUSA. In 3-8 weeks you too shall be sporting a bright shiney new gold 250K badge.
