Never disappointed, have been using these guys for over 25 years now. Always a no bs no push no up selling, if something isn’t needing to be done yet they will say so. Up front old style no bs shop. Look no further you found your trustworthy shop!

Brian was super helpful when I came in for my Lexus. My LS460 had warning lights and Brian was able to squeeze me in at short notice. I recommend this shop theyre super friendly and knowledgeable I will be returning for my future maintenances.

They were friendly, quick and down to earth. I was extremely satisfied with my service. I would use them again and recommend them to all my friends and family.

Duncan’s auto service is absolutely the best mechanic shop in the world. I mean it when I say it, because Greg and Brian are the most honest and genuine mechanics I’ve ever experienced. My family has been going here and they have treated us all like we are top customers, which truly makes this experience the best. I would recommend them to ANYONE.

Excellent place to go! Extremely friendly and knowledgeable and reasonable prices. Would definitely recommend them!!

My dad was a mechanic. I remember how kind he was with his frazzled customers. Duncans feels a lot like my dads old shop.Greg & Brian are the best. Ive been coming here for years. They are honest, patient and super fast.One example of their values: I thought I needed to replace a tire but they found that the screw I drove over didnt go all the way through. So, they didnt charge me anything to fill up the tire with air. No charge for their time!I get all my oil changes and maintenance work done here. Very fast. They often help me keep costs low.Today, I had my car battery replaced. They squeezed me in because I was in dire need of my car. Always pleasant. Always professional.And now they have a vintage Ms. PacMan machine in the waiting room. So much fun!

Greg and Brian are great, they were able to fit me in when they were super busy

Kind faces and great service. This family owned business has always treated my car like a gem, but they have not overcharged for it. Thank you Duncan Auto. My Kia and I appreciate you so much.

These guys are the best! You know how its hard to find a good mechanic that wont rip you off? Well stop looking. These guys replaced a bad starter motor for me last year and just did a rear break job. Super friendly, fast and honest. No bull here. Thanks guys for getting me back on the road!

They were very professional and honest and take care of your car at the same time.

As good as everyone says they are! Duncan Auto is a great place to take your car if youre looking for an honest and fairly priced mechanic. Do not hesitate to take your car here.

My family has been coming here since I was a baby and now Ive been coming here for about 18 yrs. Best place to go, they are very fair and truthful and quick. Greg and Brian are the sweetest.

Im always hesitant when bringing my vehicles to the mechanic shop. This family owned and operated establishment was a pleasant surprise. Reasonable service prices, prompt repairs, free diagnostics. Really a homerun having such a great mechanic shop this close to home.I recommend speaking with Brian or Greg both are very knowledgeable and will make your life much easier.

Great service at a fair price. Always helpful in finding solutions to auto prblems. I am a long term customer, about 18 years.

Duncan Auto has taken care of the vehicles of our entire office staff for years. Weve found them to be an awesome place to take your vehicle. They are friendly, helpful and do a great job at a good fair price. Thanks, Brian and Greg. From Leonardo and the staff at Insight Food Sales! ☺

Duncan Auto Service has been servicing our familys cars for over 20 years. They are very skilled mechanics who have worked on everything from our 1998 Toyota RAV4 (which, thanks to them, still runs great) to our 2011 Sienna to my moms Lexus. They are family owned and operated. Most importantly, they are honest and they wont overcharge you or perform work that isnt needed. For routine maintenance to major repairs, you will be pleased with the service you get from Duncan Auto Services.

Great family owned and trusted technicians. They were very professional and were fast with our repairs! Highly recommended!

Best people around to fix your vehicle!!! They do great work.

One word for Brian and his business is honesty

If you want a consistantly excellent experience, this is the place. Family owned and operated. Only the best work here. Exceptional, quality workmanship. Honest. Trustworthy. Friendly. Quick, but thorough.

Quick, courteous, professional. Ive had a variety of work done from bolt-on installations to basic maintenance and completely satisfied with work done. The only auto shop in town you will ever need for service, honest work and pricing.

The guys there were very helpful. My battery died and they replaced it right as I pulled up and called to get the prorated discount on my old battery. I was there maybe 20 min. Everywhere else I called wanted installation fees. So very thankful I came here!!

Nothing but good to say about these guys!! They have been my mechanics for over 3 years now and I wont leave, unless I move. The 4 guys always go above and beyond, they know immediately who I am, and I recommend them to EVERYONE!!!

I don’t go anywhere else! I moved to Seal Beach and I will continue to make the drive out here because I know I am getting honest mechanics who are knowledgeable and friendly! I recommend this shop to anyone who asks!And free WiFi is always nice!

If you want basic tune up, which I do on my own go there, if its labor intense take it somewhere else

They always treat you like family and do a great job

Great experience getting my brakes checked. Easy to work with and great price. Highly recommend

We were refered to Duncan Auto by friends from church and have been going there for several years now and trust them with all 4 of my familys cars. Honest people who do great work for a fair price. They will always give you the truth and never suggest repairs that are unnecessary.

Most honest place yet! Great staff and services. Recommended!

Good work for a fair price. Will use them again
