the transaction happened march 17th at around 5 pm. I paid 10600 dollars plus tax. the advertisement said that the car came with a list of things the car had like a sunroof,power windows, ac and a bunch of other things and upon seeing the car i noticed the car sunroof wasnt working i came to a agreement after arguing with him about it. i said you advertisedd it with a sunroof and said he would not fix it cause it cost too much and he didnt have too he only had to do the saftey. He then took money off for the car that i can accept this mistakeand i agreed. I then tried the ac and it was winter when i bought the car so i thought it was ok when i tested it and after three weeks (i have only owned the car for three weeks) the weather got warm and i turned on the ac and it didnt work. i was then told that there is nothing he can do but top up the freon because it was winter and they didnt test the ac before selling me the car and but no where in the add did it say as is, it only said it came with all these things like ac , sunroof,bluetooth,power windows and all that plus a saftey, and that he didnt have to do that he only will cover the saftey even though it was advertised with ac. He then told me that he advertised it that way because it has ac and a sunroof and didnt have to specify if it was working or not and that he is doing me a favor by even offering me anything. i then told him he can't do that and he said there's nothing you can do ill get my mechanic to top off the freon but if its anything else its too bad. i then said i will call my lawyer to see if there is anything illegal about what he did. he then said go ahead theres nothing you can do and that im lucky he was working with me. i never got a date or number to even top up the freon. pls help out with this i am very uncomfortable dealing with him as he gets rude and starts raising his voice and belittling everthing i say.
