I have bought and serviced 4 C300s from Mercedes Benz of Bellevue over the past 16 years. The service advisors are very helpful, friendly, and knowledgeable. They communicate with you frequently. Sales people are not pushy or high pressure. They do follow up if you have a question. Do you pay extra for the service. I think it is worth it.
