Worst experience buying a car. They sold me a kia forte 2014 and they never mentioned it had manufacure issues in the engine, I was just arriving to the states and I needed to get a car, I did not know anyone to advice me of where to buy a car for the first time since I didn't have credit records to lease or get an auto loan at the very beggining. They never accepted that the car was bad even though I show them reports from different mechanic garages. I see some people had good deals with this guys but in my personal experience I had such a bad time dealing with these people
