Ed and Shawn (Ed the owner and his son) always take care of me and my vehicle! I've been going to Duncan & Sons for over a decade now! I WILL NOT let anyone else touch my car! Hands down the best shop around!

Highly recommended! They took very good care of my friend from out of town who was having trouble with her brakes. They discovered a part wasn't properly lubricated and was seizing up. They cleaned off the bad lubricant, used the correct one, put it back together and test drove it, only charging $30. Given the fact she was stuck in Seattle and had no idea what was wrong, an unscrupulous shop probably would have stuck her with a huge bill. Honest, reliable auto mechanics are a rarity that should be cherished.

Ed is one of the BEST mechanics around. We worked together at Sears in Bellevue where he was my Assistant Manager. He is very productive and knowledgable. I would TRUST them with any auto issue.

I'm purchasing a car from a dealership for the first time, and called day-of to schedule a pre-buyers inspection. We were done in less than an hour, and he gave me everything from price estimates, easy things to fix on my own, what it would cost to get various fixes, explained everything in an easy to understand manner, and answered all my questions. All this for - literally - 1/4 the cost that anyone else within 30 min. had given me, and in 1/3 of the time. Super nice, and would highly recommend!

Beyond The Best!... My husband took our car in for repair. Not only did they repair our Camry, they found some nuts sitting on the manifold that another repair shop failed to put back on the transmission. They installed them! The best customer care we have ever experienced and so hard to find especially in this day and age. They are true, honest and fair! Thank you so much Duncan & Son! Will surely recommend.
