Dorso is the place to go, period ! This review is long overdue . I had problem with my Hyundai Sonata with general repair as well as MUFFLER problem. My car had problem with muffler as well as maintenance. On calling couple of automotive repair shops in fremont , i was quotes too high or vague answers on muffler problem . Finally searching google reviews and yelp reviews i finally called Dorso. The calmly explained menthe muffler issue along with fix and price (which was bit high) but were very transparent hence I selected them straight away. Dorso team sent me detailed screenshots of problem for my general auto maintenance as well as muffler work which had to be taken care by special third party mufflers experts. They made sure about each stage of work and suggested precautions even though my car was done and i am glad i kept my vehicle for 2 days extra so that they could fix all my precautionary issues. The only regret I have is i should have started coming here maybe 6-7 months earlier for servicing ! Not only are the owners and all people here knowledgeable and are in this business for many years, but they are very transparent ( share screenshots of work at each stage and message us ) and humble guys ! I already have suggested most of my friends to have their car services here :) Best of luck and thanks to Dorso team for all the hard work dedication and the quality work provide to every car !
