I took my car here for the first time when a 'service engine' light came on. I'd read great things about All Tune. All of the positive reviews I read we're VERY accurate. Dave and his mechanics were very thorough with my car when trying to detect the underlying issue. As they went along, they told me things I should keep an eye on with my car in the future, but never once tried to sell me anything or tell me I needed it right away, like other shops have. Dave was MORE than fare in the price, particularly for the amount of work. I felt confident in their work and that my car was taken care of; and more importantly, I wasn't taken advantage. I've lived in Phoenix for ten years and I've gone to several different mechanics, I've finally found a shop that 100% has my full business!!!
