My first experience was a little off. Went in for an oil change. Work was performed very quickly, however, when I go to home I noticed oil on the grill. I popped the hood and discovered the oil cap had not been replaced.
I called and tthey apologized and asked if I could bring the car right back. I did and the hey powered washed my engine compartment and front end, topped off the oil, and gave me $5 from the register to get a car wash. They also credited my account.
Overall, they turned a potentially bad experience into a show of exemplary customer service.
