  • GAD has been a great find. They've taken care of my past 2 BMWs. I appreciate their ability to fit me into their schedule on short notice and their practical and value-conscious advice.

  • I bought my wife a BMW Z3 and needed to have it serviced and a couple of things repaired. The local dealer has terrible reviews so I did some research and discovered German Auto Diagnostics. They were extremely friendly and easy to work with. They did the repairs and service as I requested without the strong-arm upsell I'm used to from other repair shops. Bottom line: Great experience, Great work, Really nice people.

  • This is an A+ quality business. I have a 2008 VW GTI and have never had any issues with the vehicle until recently. Not only did I pay  Lindsay VW $125 to basically tell me what I already knew what was wrong with my vehicle...They stated that my car needed over $2000 worth of repairs. Yeah, right. Took my car to GAD and the quoted me far far less to get my car back in working order. The owner is an honest individual and I would trust and recommend this auto shop to anyone who has been let down in the past.

  • The services provided by the German Auto Diagnostics STAFF were outstanding! I took my 2004 BMW 645Ci to the shop to ascertain the cost of several repairs and received a fair and honest estimate. The repairs were completed and my car was ready for pick up, as advised.

    Based on my experience with German Auto Diagnostics, I highly recommend this shop to ALL who are in need of any auto repairs. The entire staff was friendly, courteous, and professional – I believe they LOVE the work they do!

  • Shir and his team at GAD did an excellent job at rebuilding the transmission on my car. Even do they could do the work themselves they preferred to send the car to the best transmission specialist in the area. I will like to say the car runs fantastic is like brand new, I am very pleased with their work.
    Shir is an honest, trustworthy, dependable and friendly  mechanic you are always looking for to work on your cars. I know I will be using him in the future. His facilities are bright and clean so are the repair bays. Highly recommended.

  • I scheduled my MB E430 here after about a 2 yr absence and learned it was under new ownership. From the moment I walked in to the moment I left, the service was very, very attentive. I waited for my car and was asked if I wanted any beverage, later asked if the room temperature was comfortable and when it came to what needed to be done on my car, I was brought into the service bay and shown everything that needed to be repaired, as well as what needed to be done for my safety. I was very grateful for the fine service and thought the costs were very reasonable. I would definitely recommend GAD.
