Mercedes-Benz of Walnut Creek

What has happened to Mercedes Benz of Walnut Creek. The sales department seems to think they can do whatever they want. Customer service is not part of their philosophy. Squeezing every penny out a customer is what they are about. No integrity, no morals, no soul. They mislead, lie and and act as if you do not have options. I have purchased new SL class here in the past. This time I was purchasing a used Mercedes, maybe thats the problem not enough markup. They treated me disrespectfully and were shocked when I walked out. I never had a bad experience here so why would I heed the warnings of bad reviews. So go there and wait till it happens to you, then you will not be going back either.
