AutoNation Chrysler Dodge Jeep Ram Spring

I found a car I wanted online and called to make an appointment to see it. I was offered WAY LESS for my trade-in than any other dealer I have gone to. They finally agreed to $1K more for my trade in (still less) so I settled. (MISTAKE) I have almost perfect credit but they wouldn't offer me any less than 8% interest. I just agreed and figured I would refinance right away. Took home my car that night and it was filthy inside and they said they could not put gas in it. The wipers were also worn and it rained on the way home so I couldn't see at all and the gas light came on during my ride home. The dealership also said they couldn't put on my paper plates due to a screw or something, but I did it quickly when I got home. I like my car but this is the worse buying experience I have ever EVER had.
