It seems that a lot of service type businesses take their vans and trucks there, so maybe those guys just always have precedence over regular people off the street. They were fine as far as work done, but I probably wont go back there. Why go back if takes them almost a work week for what is maybe a 5-6 hour job. I have no idea why they get such high ratings, and people rave about them.
At Cunningham Brothers we strive to be thorough on every job. Occasionally we fall short. This customer had to bring her car back for a minor issue after having a timing belt replaced. We took care of her car immediately. She brought it back again later for issues not related to the timing belt job. Even though it was not related to our work, we took care of it at no charge.
Only thing I would change is opening at 8a and/or closing at 6p, and maybe having 1 Saturday a month for the schedule flexibility of the customers. For those of us that work 8-5, we have to lose time from the job to take care of very important car business.
