Yes,they know. When I first got the car, they told me to drive it around for a few days and bring it back to them to smog it. I did that and it still wouldnt pass smog. They told me to leave the car with them and they would take it to a tuner shop and have them fix it. It was suppose to only take a day or 2 but it took almost a month. They couldnt get it to pass smog. So when I ask for my down payment money back, they tell me the sale is final and they cant do anything about it. They keep trying to tell me they will fix it but its been over a month now. Thats why I need to know what my options are here. This whole situation is shady
