So gald I found Kahlers. After horrible experiences at the Pleasanton Mercedes dealer I finally said "enough" and found Kahlers. They were wonderful, honest, fast and reasonable priced. To put it in perspective - I had a light that burned out on my car and the dealer charged be over $125; the same light on the opposite side was replaced by Kahlers for a cost of $25. If you still go to the Pleasanton Mercedes dealer - STOP - and go to Kahlers instead.
