car not in a good condition to sell to a third par

I bought a car 2012 at GMW in gateway 2012.the transaction was cash. I was young and a first time buyer.I was taken advantage of.the car had and still had a disc stuck inside.it was painted the same day I picked it up.so no polishing was made.the engine is Ford focus.the paint is fadin has faded to white.few days after taking the car I had battery problems.I don't want the caranymore but cant even resell it.its a disaster...advantage should not be taken on females drivers by the sales representatives.this car has been nothing but costly.on my attempts to fix the radio Steve used to make me come to the office and he won't be there and make excuses.even now I can't play the radio.my first time buying a car became a disaster.and even now it is.this car is bad.
