I was quoted $18 each for some Bosch Platinum plugs at the dealer. When I balked at the price, he dropped it to $13 each. Told him to keep them.

What's really sad is that this just adds to my "I'll never buy another Mercedes as long as I live" feeling. It grows every time a stupid light comes on in that ML dash or I'm asked to pay 900% more for parts than my Chevrolet driving bretheren.
