Now from the Dealer side. As I have worked at MB dealers for 28+ years, I believe that almost all of the people that I've met who work for dealers are honest. As in any business there are rotten apples who can spoil any thing. In today's business world this type of person won't last long staying in one place or dealership. One thing any one can do, is check with local BBB on the number of work related complaints. If the person working on your car can't explain the nature of problem OR why your car isn't performing properly then you need a second opinion from someone who does & will take the time to fully satisfy your needs!
