Nationwide auto Finance LLC Sold me a faulty car and charged twice as much as it's worth they won't trade it in or give me at less half of my money back Oregon Ohio

 When I went to get the car the sales person gave me 10 minutes to test drive. He told me they do inspections on their cars an would inform me of any problems when I talked to management he said that was a lie they don't inspect their cars. The man that sold me the car didn't let me read the contract he said he'd just explain what it says I trusted he'd be telling me the truth when I finely did read it the contract says "DO NOT SIGN BEFORE READING" several times. The keys didn't lock the doors which I found out the hard way a police officer had to help me get in the car. Finely the car stopped working three weeks after I got it I had to have it towed to them they told me I could sign off on the car an put another Deposit Down on a different vehicle I've given them 1352 so far in three weeks an they just want me to sign off.
