bought a used 2000 gmc sierra from them with a 3 month 3000 mile warranty. took it back a month later with in the time of the warranty because an oil leak and transmission leak. they told me the oil was from previous a oil change and the transmission bolts were loose and the tightened them. which this did not come close to solving the problem, by the time I noticed the oil and transmission fluid again my warranty was up. turned the oil leak was the rear main seal which explains why they did not want to spend the money to repair it and honor their warranty. the cause of the transmission leak was never determined even after servicing it and replacing the pan gasket myself, it still was leaking somewhere above the pan around the shift linkage.
