<human>: Give me the gist of the text in a nutshell

Ok so the backstory is that I have been working hard to save up a good chunk of money to buy a car. Well the day finally has come when I feel comfortable enough to buy a car. So I go to the lot and start chatting with a dealer. I test drive three cars, lets call them; Car A, Car B, and Car C. Well I fell in love with Car A which was the pricey one of the bunch, but was reasonable if I got a good interest rate on. Mean while Car B was eh and did not appease me at all and was still pricey, and Car C was the cheapest and I did not like it all. I felt unsafe in due to its size. Well we go inside and start running the numbers and scenarios for Car A. We spent hours upon hours dealing for Car A and it was just a bit of my range. So I went out to the lot to look at other cars to see if anything else would catch my eye. Before I even get done assessing the second car the guy from Finance comes out and says that he got the numbers for "The Car" down to my range. I am beyond excited and I go back into his office he tells me that he got the "orice down by texting" the bank financing the car. So I sign all the documents that are mandated when buying a new car. I am the happiest man ever. Well I walk outside his office and I am about to leave and then the dealer calls me over to his desk to talk about the last details like when I can pick it up and what not. He quickly says that the reason the price went down was because I had actually just bought Car C. I had not been told whatsoever that Car C was what I was signing for. I asked what do I do? He said there was nothing to be done besides void it out. I want more. I was lied to and taken advantage of. I was never informed that my purchase had been changed.
<bot>: I went to buy car. I bought a car. After I bought the car I was informed I had actually bought a lesser car. Do i have any legal action.
