I took my diesel truck in for an unscheduled oil change. Since I didn't have an appointment, I expected to have to wait. Shawn told me that he would still be able to get my truck even though they were busy. Turns out, since my truck is diesel they are particular about who works on it and I had to wait longer than they thought I should have. I didn't complain. But, they didn't charge me for the visit because I waited so long. Wow, it was a long wait. But, a diesel oil changes cost over 70 dollars and their customer service department valued my time such that they ate the cost. Thank you Lane Buick GMC. I'll be backl.
