I've used Haas for all of the work on my various cars for the last 15 years. Bill and his staff are knowledgeable, competent, and honest. I've gotten rid of a car or two based on their findings. In all of my dealings, I've only once ever made a return trip for an issue, and it was the result of a miscommunication. I do not hesitate at all to recommend them.

Excellent service, very professional, and listens to the customer's concerns. TRUE STORY: My son's Mini Cooper broke down, and the insurance company picked up the vehicle and towed it to one of their recommended BMW shops. The insurance company shop called for additional authorization of $150-$300 for further testing to determine if the engine needs to be replaced between $12,000 - $18,000. I declined and pick up the vehicle and took it to HAAS auto repairs. The owner, Billy, has worked on the car many times and provided excellent service. HAAS called me the next day, indicated they removed rear value cover & found the casing plugin cylinder head between the camshafts came out. I pick up the vehicle for a fair price. MY SON CAN COMPLETE GEORGE MASON WITH HIS VEHICLE. GOD BLESS.

I've been taking my vehicles to Bill for 27 years. His team goes above and beyond to ensure they provide quality craftsmanship and you are satisfied with their timely service. I would highly recommend Haas Automotive for all of your auto repair needs.
