Bill Haas provides highly competent service on our cars at reasonable prices. He is an excellent diagnostician and doesn’t have to guess what needs to be fixed. I trust him implicitly to keep my cars running well.

Friendly, fast, and fair priced. We were so happy with the turnaround ad prices we took our other car in to them. Gives a price and sticks to it. They don't pressure to do more than necessary but will at least let you know when something else will need to be fixed again not pressuring you to do it then and there. Highly recommended!

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.
