Great Service

Great service and knowledgeable mechanics. I appreciate there honesty above anything else. I only paid 2k for what I had done but unforseen circumstances led to a valve adjustment, a valve adjustment on my truck is hard and not many people know how to do it. They brought someone in to do it and I know it was approximately a $800 value that they did not charge me for. I plan on paying them for there generosity.
