Cherry Hill Mercedes Benz dealership

I purchase Mercedes GLK350, 2015 model from Mercedes of Cherry Hill, NJ on 4/20/2015 and went there to pick up car at 5 PM on 4/23/2015 as promised by the sales representative Joe Zalof. I had most disappointing experience of my car purchase at the Mercedes of Cherry Hill, NJ that I want to share with you for appropriate action. I arrived at the dealership at 5 pm on 4/23/2015 for car pick up; however, Joe did not attend me until 7:30 pm as he was attending another customer. Joe completed my purchase paperwork at 7:30 to 8:30 PM, and spent 15 minutes about the car operation. At the time of car delivery, I observed that car was very dirty, there were birds droppings at the roof of the car and tires were full of dirt and mud. When I showed birds dropping on the car, Joe shamefully started laughing and said that he considered that as good luck. It was quite clear that Cherry Hill Mercedes dealer did not do detailing of the new car for delivery, It was getting quite late and my trade-in car was already taken by the dealer, I accepted delivery of the dirty new car but asked Joe that I will bring car back for full new car detailing delivery service after I return from my vacation trip on 5/10/2015. Joe assured me that he would get that service done when I return. After returning from my vacation on 5/10, I called Joe several times and left several voice messages for him to let me know when could I bring the car back for detailing and learning more about proper operations of the car. I also reported that 1) car was running at 100 degrees on the temperature gauge and if that was normal or abnormal, 2) car's garage door opener was not working, and 3) I had not received my car title from the dealership as car was fully paid. Joe did not return any of my calls. After waiting through 5/19, I call;ed the sales manager and reported my experience and frustrations of purchase of new car at Cherry Hill Mercedes dealership. He told me to bring the car to the dealership on 5/22. On my taking car to the Cherry Hill dealership, the sales manager got the car washed without any additional detailing. He also asked Mr. Diago to help me for various operation of car, Mr. Diago was quite helpful. Electronic verification about running of car at 100 degrees on the temperature gauge was not checked by any mechanic, rather sales manager showed me another GLK350 was also running at 100 degrees on the temperature gauge. He further told me that since I lived more that 15 miles away from the dealership, he can;t send anyone to fix the garage door opener operation and suggested me to call the Mercedes road service. I ended up arranging for fixing garage door problem at my own expense. My car title was sent to me by late-June essentially two months after purchase of car. I thought that I should share my poor and unsatisfactory experience at Mercedes of Cherry Hill, NJ so that Mercedes-Benz USA office can look into it. I have no plan to go back to Cherry Hill dealership for service as my past experience at Ray Catena Mercedes, Edison, NJ has been quite good. Sincerely, Mohinder
