Ackerman's is very considerate and helpful. With two children, I need service that finishes on time and respects my limitations. They are very accomodating and polite. They even send a thank you note after servicing the car. Honest estimates too...just when you thought they were merely starting figures. Needless to say, this level of service does not come cheap. But they are independent, and I find they deliver on the premium charged, whereas many dealerships take advantage.
