Ok until three days later the car they said was fine and their mechanics had looked over had a warning light pop on. Needed a new alternator when I contacted them they said to take it a dealer to have them look at it. They then refused to pay for the fix. I explained that the sales rep said to bring it back if anything strange happens or doesn't work and they would take care of it. He was just saying whatever he could to make the sale. They did pay for half the fix out of good will after arguing. A quality dealer would have taken care of all it after just 3 days! 3 DAYS! The dealer I took it to said they could not believe they were refusing to pay for it. Ford should be ashamed to allow them to be a certified dealer.
