What should i do if i got cheated by the dealer and how can i share my bad experience with the rest?

The dealer was MR CARS AUTO SALE. I live in Philadelphia PA the dealer is in Elmhurst NY. Before going
to the dealer i looked at the pictures of the car and liked them. Then I called the dealer and asked him
questions about the car if for example it had any shortcomings and the answer was that it didn't have
any problems and was in "excellent condition" (as he said). Then the dealer told me to give him a
deposit because he told us that he could sell the car to anybody else. Being scared that we could
lose such a good deal I paid him the money.
I asked a guy who had to take a day off to help me tow the car, traveled almost 225 miles in both
ends, spent 50 dollars on gas and 45 on tolls, suffered for a long time in NY traffic and what i saw
didn't come up to my expectations. The car was horrible- the front passenger seat was a little bit
torn, the right mirror was broken, one of the switch buttons for the cd player on the steering wheel
was missing, and the car had two holes on the roof filled with black silicone though the car itself was
white so you can imagine how it looked like. It was not what I had seen on the pictures and the
dealer had lied to me that the car had no problems at all. He kept insisting that the car was still in an
"excellent condition". If this car was in an excellent condition according to him I can imagine what his
other cars which fall under  category "good" and "satisfactory" look like!!!  When I refused to buy this
car he in his turn refused to return me all the money i had paid.  He told me that he would keep $300.
So i got cheated and lost my money  and time. I want everybody to know about this awful dealer to
avoid such scams!!
