Prestige Exotic Cars Sales Inc

Let me start by saying that I NEVER write reviews about companies but I am very upset. I bought a car here recently and I am very unhappy with the two-faced owner and service. I bought a used car for 4500 and they charged a "doc fee" of a $100, somehow the total was 5000. i asked why i have to pay 5000(cash) they told me it was for the registration and tax which made sense how ever i asked for a reciept with the total amount but they would not give it to me and said "you have our word". I went in about 7:30pm so they told me they cant register it at the time however they would give me whatever was left over after everything has been added up the next day when my brother went and pick up the car. I personally added everything up and they shorted me about $50-70 which im not too mad about. the thing im mad about is that the owner of the lot promised to have my car cleaned, washed and inspected with a PA inspection but when my brother brought me my car it was dusty and not inspected in PA. The car is not bad but they really lost my business because they cheated me for some money and lied to me.
