At the recommendation of a friend, I decided to bring my aging Honda Civic to Diablo Auto Specialists when my transmission was acting up. They were great from start to finish - kind & informative on the phone & in person, I was able to drop off/pick up my car after hours, at my convinience. Tim kept me informed to their progress over the week that it was in their hands, parts were ordered quickly (overnight). Since then, I have brought my car back to fix a chronic AC problem. Come to find out a few weeks later that the problem reoccured so they revisited this situation and found that there was an ajacent problem and fixed it for good - they didn't charge me for this work/parts as they felt they should have found it earlier. These guys work with integrity which is hard to find these days! They have a customer for life - thank you Diablo Auto Specialists!
