Walnut Creek Auto Repair

Honest and professional...what more can I say?

Great service every time I have come in; thorough and transparent. Highly recommend to anybody.

I had my car returned on time and was informed clearly about the work done and the condition of my car. I had a few questions and Tim took the time to answer in a way I could understand.

We've been having our 3 cars serviced at Diablo Auto Specialists since they opened -- wouldn't go anywhere else. They exemplify the highest integrity in all that they do, from start to finish. Tim & Cathy run a first-rate business, and we're so grateful to entrust the care of our cars to them. They are friendly, thoughtful, and honest -- welcome qualities in any business.

Great service with great attitude. Never feel that I am overcharged. Always know that the job was done well. I trust their work.

Diablo Auto is highly reliable. Unlike some service shops, they don't try to up-sell or over-charge. So I rely on their advice concerning which repairs are necessary to prevent trouble, and which repairs are optional or can be delayed. Tim has also been kind and helpful in keeping track of our vehicles' repair records. He is patient to explain the technicalities in detail. He's gone beyond the call of duty in researching alternative sources of special parts and enhancements.

Great service and on time. Thanks for getting me to my appointment.

I am a long-term customer of Diablo Auto, and I continue to be very satisfied with the quality of their service.

I ALWAYS FEEL COMFORTABLE AND AT EASE BRINGING OUR CARS TO DIABLO AUTO, BECAUSE I BELIEVE THAT SERVICE IS EXCELLENT AND TOTALLY TRUSTWORTHY.

Great service and results from Tim and crew. Truck runs like it just came off the lot. Good sound advice and quality workmanship.
