It was the worst experience of my entire car buyin...

It was the worst experience of my entire car buying experience.
It is a long story but please take time to read it as it is word by word true and will save you from getting cheated and all the issues as they will sweet talk you by saying that how they are oldest mercedes dealership in PA and stuff, maybe among all the BS they will tell you, this is the only truth they would tell you.
The were trying to sell me a car which had been into an accident without disclosing me about it. I am from KY and I was interested in buying a preowned Mercedes Benz CPO S550. I called and spoke with the salesman name Andy Fox, who pretended to be very nice. We negotiated a deal on the S550 diamond white VIN number WDDNG9EBXDA523886 and stock number MB6682B. It had a clean carfax and I specifically asked Andy Fox that if there was any physical damage to the car or had been that I need to know. I explained him that I am coming all the way from KY which is almost 500 miles away from you and I don't want any surprises. He assured me that it is a great car and I would be very happy to see the car. We also made me purchase the insurance on the car before even looking at the car, which was reluctant about but still did it as he was like "if you don't have insurance, don't even make a trip, as we will not release the car". So I did, even though my state farm agent told me that I don't need it, as they cover the new aquire up to 3 days but no issues I purchased it. I also hired someone to drive me there rented a car as I didn't wanted to put almost 1000 miles on my car. Andy Fox specifically told me to arrive by 12 noon and he will have the car ready. By chance we arrived early at 8:30AM. There dealership was closed so we drive around and luckily found the car standing out in the lot. The front chrome trim was falling off very obvious and the front bumper was completely misaligned, from one side all the way in and other side hanging out. I was really upset, as we just drove 8 hours. We waited and came back at 9am, when they opened. I saw Andy Fox and asked him to show us the car, he took us to the car and I showed him the damage and surprisingly he completely brushed me off and said I am mistaken and its not that and whenever I tried to talk to him, he kept running away pretending that he is super busy and run away, when we were the only one in the showroom as that early time. Then this guys has a nerve to take me to his manager Tony Seyfert and tell me to start signing the finance paperwork. That moment I completely lost it, I was like this car is damaged and you are not even listening to me and stuff. That moment Tony stepped and asked me to show him what I am talking about. I took him to see the car and he agreed about the damage and told me that the previous owner took off the bumper and got it repainted, so just by looking he knew about that car but never disclosed it to me. Then I took the car for the test drive and realize that the thing where the seat belt lock in for broken and was fixed with the transparent tape and the doors were shaking as if the car has been into a collision and have shaken the whole car up. It took 60 seconds to get the sunroof open and they said it has a slow Motor. Just for everyones knowledge this is there so called CPO, that goes through that 152 point inspection and stuff. This car was a junk. Then when I asked why there is nothing on Carfax, Tony tells me that Carfax is not 100% reliable and things can happen to the car which is not reported. So don't even trust there cars carfax as they will fix accidental cars and will mention it on there records and hide them for customers. I am glad I did not buy a 1 sided airplane ticket as I would have been completely screwed.
Save yourself from getting cheated and don't trust these people and don't buy anything from them because they are bunch of scammers.
It was along story but a true nightmare experience of mine, hopefully you will read this and find a different dealer to buy your mercedes or any car that they sells and save yourself from the horror.
