Had taken in car unscheduled due to wierd hissing/squeaking noise. Had a road trip to San Diego planned for Labor Day holiday, and was leaving in just 3 days. Nat'l Automotive able to quickly diagnose the problem, rear brakes, and was able to handle this, again unscheduled, along with an oil change and maintenance, on my only day off that I could have the car there, in just about 3 hours. Saved my bacon. Thanks a lot Randy, Tom all the folks at NA.
