RPM AUTO SALES Scamers BAYVILLE New Jersey

I bought a 2006 chrysler 300 on Feb 24 tryed to have 1/2 of the price of the car financed filled out the app and waited for the bank call in the mean time the sales person made comments if i had that much money to put down on this car ect. The bank called back and at that time where everyone is financed I was turned down that was fine at this point i aske him what was the lowest he could go on the price and again he asked me if i had that much money i started to feel some kind of way but i kept going because at this point had put in4 hours at this dealer, He came back and told me 13000 I told him i saw it on the web sight cheaper he went back and looked it up and said yes 8400 i asked him if i paid cash can he go any lower he said no i told him to start writting it up he asked me again you have the money at this point i said i woulnt tell you to write it up if i didnt took the car home drove great about 3 weeks it had gotten a bad whoble in the front end brought it to the shop and it needed 4 new tires another 1000 this car had issues when i got it bc it had antifreez in the engine compartment the way it overheated before now it needed a new radeator replace now my warenty is up hmmmm junk yards give you a 30 warenty on there parts why is it that a dealer is only giveing me 30 days well right now i paid 9360 CASH to the dealership then within 3 months paid another 1000 on tires and now the best is yet to come the car is sitting with what we think is a blown motor  THAN YOU RPM for selling a pice of junk car to me
