"I had a deadline to meet and didn't have my vehicle, as it was being worked on 3 1/2 hours away. I was not sure when my vehicle would be returned. This was not a problem, they were so polite and accommodating. I got an appointment and was to call if I needed to change it, just give them 24 hours notice. Top notch service!"
