I ordered a transmission replacement and after the transmission was shipped and arrived, I had to cancel the order. Obviously this was not a pleasant thing for these folks to have to deal with. But they handled this with grace and understanding and refunded my full deposit. I am very impressed with the value they place on customer service and I certainly recommend them to anyone who values that!

Once again Superior did an excellent job with the maintenance of my vehicle. My car is old (1999 Toyota Rav 4) and Superior has helped me develop a maintenance plan to keep the vehicle running for another, hopefully 50.000 miles. They communicated frequently with the status of repairs and kept me up to date with the schedule and outlook of completion.

When the vehicle was finished, it felt like I was now driving a new car and ran so so much better. Im grateful to Superior, especially the mechanic, Chris T and Service Advisor, Kyle O. for their superior work and for great communication with the repairs. Its nice to know I have such a great and consistent team for my car maintenance

Moved to Seattle and needed a new reliable place to take my car. Found SAS as a AAA certified repair shop and took my car to get a headlight repair and oil change. They did an inspection and let me know things that needed to be repaired along with a quote. A few months later I brought the car back and they stuck by the quote fixed everything for ~$100 less than a nearby store. I do wish there was a shuttle service or way to get someone to drop you off somewhere close to their shop since they close for an hour each day.

Not a great experience. Went to have my AC compressor replaced. Incorrect part was ordered twice delaying the repair. After installation, they tried to charge me $200 additional dollars to 'diagnose' a blown fuse on the AC circuit after I had paid $1200 for the compressor replacement. (took 30s and a $1 fuse at home). They told me my radiator was leaking, probably because I had just flushed my coolant and made a bit of a mess in the process. I confirmed at home there was no leak.

I love this place! They are honest with me, and never made me feel like they were out to just get my money. I love that they tell you what is most important and what can wait. Prices are more than reasonable for services, which is great, and I like the early hours; you can drop your car off before work. I recommend them to anyone in the area. If I had to say one thing, I wish there was a time estimate for services.

As someone who doesn't know cars at all, it would be nice to know when booking how long services take (an hour, a day, overnight, etc). This would make it a bit easier to plan ahead. Still love them though!

Have used Superior Auto Service for a couple of our cars now. Needed a timing belt replacement and full fluid service on a car we had recently purchased, so i got multiple quotes from shops. Superior Auto Service answered my questions quickly and offered the best quote out of the 4-5 shops I contacted, even including the water pump and belt replacement that is optional on timing belt jobs.

They did great work and they do the most detailed vehicle inspection I've ever experienced which was very helpful. It took them a little longer than expected so I was given a discount which was very appreciated. When we took our truck there, we had a belt replaced that ended up being noisy when the engine was cold, and Superior Auto didn't hesitate to get us right back in for a free repair of the faulty belt. Overall, fantastic customer service, very thorough work, honest people, and reasonable prices. Shops that truly stand behind their work seem to be getting more and more rare. Thank you Superior Auto Service!

Quick, honest, transparent, and does quality work. brought a car out of storage for an inspection and was provided a very thorough report and frank discussion of options. They were comfortable discussing priorities and doing some work and waiting on other items. inspection + work they had my car for just over 24hrs.

These guys are always stellar in regard to customer service as well as quality of car car. While my car was being serviced by them, I went to walk around the neighborhood, and ran into a lady who also happens to be their customer. She too shared with me how satisfied she is with their service of her car and that they have saved her car which she previously serviced at a shop that almost ruined it.

It was lovely to run into a complete stranger who happens to have the same positive experience as I do with these wonderful people. She also led me to a little library where I found a fantastic book on health, but that's a whole different review.

I cannot speak highly enough of this place and every single member of their staff that I encountered. We brought our car into Superior Auto Service after we had some repairs done by another shop, but then it gave out a horrible death rattle and wouldn't start. The guys at Superior Auto not only found and fixed the problem the other guys missed, but they identified a number of potential future issues and detailed them out for us with a timeline of how to keep our car running.

I have never found a more honest and genuinely helpful group of mechanics. These guys are proper Old Seattle, focused on good old fashioned customer service and honest dealings. Seriously, I cannot praise and recommend Superior Auto Service and every employee they have highly enough. If you want good honest dealings, it doesn't get better than Superior Auto.

I have nothing but great things to say about the service here. I brought my van in for an initial inspection on a whim and Scott (shout out to Scott in particular as he worked with me the most), Keith, and the entire team of mechanics have been fantastic in solving all of its issues. They explain what needs to be done and what doesn't, and they stand behind their work. If you're looking for an honest shop look no further! Picture for fun, as without their work my van wouldn't be able to have fun pictures!
