When u look at the oil dipstick make sure that its clean all the way up. There should be no burnt oil on it. Take it for a road test with the radio off drive it at city speeds (25-35) then take it on the highway (65-75), make sure u dont hear any strange noises. Also look at the brakes (Pads, lines and rotors). When checking the exhaust take a rag or a towel and hold it over the exhuast tip and make sure u hear no leaks. HIH
