Service is Friendly. My only Gripe is the Cost. My 6.4 2500 costs me 130$ for an oil change. I asked him why it costs so much and he said the oil alone was 80. I find that odd because I have been changing my own oil for the 3 years ive owned this truck and the oil, lucas stabilizer and filter have never costed me more than 55$. Something just doesnt seem to add up. Also, i asked the clerk not to touch the tires/psi because it had just came from a shop and my truck had been calibrated to the tires max psi. What did they do? They Adjusted my tire psi to the door specs putting all 4 tires over 70. So i basically paid for something i specifically told them not to do. Moving and all my garage stuff is packed is why i brought it in. Again, nice people but prices to me are suspect. Make sure when you bring your vehicle in, you get a quote. If they wont do it, take your business else where.
