One more thing.... If you are buying a used vehicle...I don't care if the Pope is the salesman, get a mechanic to check it out. Also do a Google search on any recalls or complaints on the year of that vehicle. Some years of vehicles are known for certain problems and those vehicles are traded in or sold at auctions frequently. Watch for smoke, you need to drive it at a good speed and let it get warmed up to see how it does. If you smell antifreeze check the heads or actually, don't buy it. If the car lot won't let you take it to a mechanic you trust, don't buy it. I tell everyone who buys a car from me to take it to their mechanic. You can have auto zone run codes for free during test drive. No dummy lights do not mean no codes. A lot of used car lots clear the codes but don't fix the problem. Same advice for CL. Good luck.
