We purchased our car from this dealership and had a good experience. Unfortunately, their service department is probably the worst of any service department I have used. When our E550 only had about 1000 miles on it the brakes started grinding pretty bad. My husband called service and the response was, call roadside and have it towed to us. No, we don't have a courtesy vehicle, no we don't know when we will look at it but it is not safe to drive. I thought that this was a bit of an overreaction, and because we live so close (and I could not go without a car) I arranged driving in early in the morning when they said that they had a courtesy call available. I showed up in the morning (after being up all night with a teething baby!) and they informed me that there was no courtesy car available. Then, of course in this situation it was OK for me to drive back home, and make another appointment - which contradicts what they said on the phone about the car not being safe to drive.
It gets even better, we got an email saying that we were a no show for our service appointment, and when we reached out to management to discuss this, and the fact that they really inconvenienced us, there was no response. So, we ended up calling Littleton Mercedes, we explained the problem with the car, they told us on the phone what they thought it was, and we drove in, got a courtesy car and got the problem fixed. The service at Littleton is so much better, so I recommend taking your car there instead. In fact, we will drive down to Littleton when we get buy our next Mercedes, we won't be doing business with Denver Mercedes ever again.
