I purchased a used car yesterday and the salesman misrepresented the gas mileage. He told me it was 25mpg, it is actually 18mpg. I know I should have researched before I purchased. I went in for one model, but found out I could not afford it. I had asked for another car I had seen online and he kept showing me different ones, and then I got suckered into a different one. I like the car, but would not have gotten it if I had known the gas mileage. There was no sticker on the car or anything, it has just came out of detail. I feel like I was tricked, is there anything I can do???
