Went here to service my GMC truck as I like to support local businesses. I bought a nice GMC Medium duty truck and didnt really know much about diesel rigs, so I just told them to look things over and change the oil, etc. They checked my fluids and changed the oil. Price was over 500.00. Shame on me for paying that but being new to diesel trucks, etc. I didnt really know what to expect. I asked why so much and was told it was a big truck and a big job. In talking to diesel owners they were stunned with the price and said it should have cost not much more than a std oil change. Lessons learned, do your research beforehand. I went in blind about my vehicle and unfortunately paid the price.
