"Certified Pre Owned" car just cost me 3.5 hours of work time, 1 gallon of gas for them to run my car and test the engine and $70 dollars.....for..... .5 gallons of antifreeze. After 2.5 hours of sitting in the waiting room I went to find out why I hadn't been talked to yet. They were all on lunch. They had no clue what was going on with my car. After going to find out what was wrong they told me they were still testing the pressure for low coolant. Another 45 minutes passes before they come and find me, the last person left in the waiting area, to tell me its finally ready. Unless you can prove its a mechanical defect their warranties are worth nothing. Unless I can prove it is mechanical I am NEVER taking it back to them. They are scam artists. When this coolant runs out again I am expecting a FULL REFUND and an apology!
