Duncan’s Auto Service

I trust these guys with every car I have.
When my family moved to LA, they drove the extra hours to bring their cars here
My girlfriend’s family recommended them to me and I have since recommended them to everyone I know. These are good people that remember you and your car and they care about how you specifically treat it (Whether that be cheap like me, or expensive like my dad)
I tend to do most of the preventative maintenance on my vehicles but I know that when something goes wrong on my girlfriend’s car I can send her in and all she has to do is let them know what’s going on, they look at it, fix it and give us a fair price and a reason for all of the work.
WE HAVE NEVER HAD A PROBLEM HERE FOR 6 YEARS!!!
One time, my girlfriend mentioned that I like to do the routine work on her car when they changed the fuel filter or something without asking first (it needed it real bad) so they took off $ 10 and they have always been so good about calling us ever since.
I have never been more happy with a mechanic and will go here as long as I live in Southern California.

I just brought my car in because the check engine light came on and this place is close to where I live. I had trouble finding them so I called and right away I could tell how nice these people are. When I found them they immediately made me feel comfortable. Brian sat down with me and explained the problem and what they were going to do to fix it. He was so genuine and real with me, and gave me a good price. I got screwed by the last place I went to, but I’m so happy I’ve found Duncan’s.

Highly recommend this shop. I took my 2005 Honda element there to get the alternator fixed. They quoted me a price and the car was done several hours later. Would go back again.

BEST AUTO SHOP IN THE OC!
Took my Honda Civic to a certified Honda dealer and the head mechanic couldn’t even figure how to fix my AC.
WHEN I took it to Duncan, they were able to fix it in a snap! Thanks Brian. Now driving will be much more comfortable.
What are you waiting for Unilocalers, you found your new auto shop!
Fist review here and I have been going to Duncan for 25 years, granted I’m 25 but my father has been coming here before I was born.

Duncan’s is a great place for car repairs. Gregg, Dwayne and Bryan are honest and reliable. I trust hem with all my repair work.

This is my 2^nd review on Unilocal and maybe it affects my credibility but Duncan’s crew is one of these old school shops that will work with you and you will go home happy.
I have been a car enthusiast almost all my life with a decent amount of knowledge– DIYs under my belt, and also have dealt with mechanics from all kinds.
This is a shop I trust, happy with and will come back again.
thanks Ducan“s

Been going for 25 years! It doesn’t get any better than Duncans!

These guys are awesome. They are the only auto shop around that won’t encourage you to get unnecessary work done on your car. They tell it to you like it is, and with a smile at that.

We’re back in CA! Our first visit was to Gregg who didn’t charge us to check out our truck from Texas and keep it at his place for a week. Just love these guys..

I like many of the other Unilocalers started going here based on the recommendation of friends. This is by far one of the most honest mechanics I have ever been to. Not mention Duane and everyone I have come into contact with are the nicest friendliest people I have ever seen — it’s like they actually like their jobs…
They do not try to upswell you to add to their bottom line and tell you like it is.
My whole family has started going here as have many of my colleagues at work and friends as well. On a recent visit my sister took her car in and they suggested what needed to be done but also told her it’s not with the money to keep repairing the car — that she should look into getting a newer one. Who does that? Wouldn’t you think they’d be like keep bringing it in (the sound of the register would keep going cha ching).
I cannot recommend this place enough!

My wife and I have been using their services for about 10 years and never once have I been dissatisfied or even questioned their work or recommendations. Greg and Duane are always upfront in explaining what other work may be needed after pulling things apart. Once they even recommended I take my car elsewhere to save money when they couldn’t replace the transmission themselves. Honesty and integrity at its best! Thanks Team Duncan!

These guys are top notch and very honest. I just cannot say enough good things about them. Once I took my car over becase it was steaming and smoking one night and I thought it had a water pump issue. I did not look too closely as it was night time and I just took it directly over there. It turned out that I had stored a small plastic funnel in the engine compartment and it had become dislodged. Gregg noticed this gummy stuff on the manifold and called me about it. We talked and I realized what had happened. He charged me nothing for my boneheadedness! I picked up my car up late and slipped an envelope through the door with some $$ in it. Since when do you have to FORCE your mechanic to take your money?

My entire family has been coming here for years. The customer service they give is exceptional! I always feel they are doing things that are in the best interest of me and my car. They are honest, friendly, reliable and trustworthy.
I will never use another mechanic as long as these guys are around.
And if something isn’t satisfactory when you drive away, they will always make it right.

Can’t believe I haven’t Unilocaled Duncan’s yet! Duncan’s Automotive is a reliable, honest and friendly business! We use them all the time, we have four cars and they all have visited Duncan’s! Thank you Greg and Brian! We really appreciate your knowledge and friendliness!!!

Duncan auto service is top notch. I have and will take all of my cars there for the rest of my life. They are knowledgeable mechanics that will do the job right and not charge for stuff you don’t need. I wish they offered other services so I could pay them for that too.

Been going here for years, take family members cars there I recommend them to everyone. Duane and Greg always upfront and straightforward. No hard sell here. This place is the place to go! A example for all other mechanics! Not enough good can be said. Honest. Realistic pricing. Great work! Why go anywhere else? Moved to LA and I still take my car there!
Still not sure why my review was marked as a not recommended but hopefully some will see this!

Like most, I normally hate dealing with auto mechanics, and I try to avoid them as much as possible. It’s not easy to find a shop you can trust. Yesterday, however, I found this place on Unilocal,and they have already made a loyal customer out of me.
I needed an idler pulley replaced, and Brian quoted me a fair price, but I assumed they would inevitably find something else to charge me hundreds of dollars for, as most mechanics tend to do. Not at all. Duane replaced the pulley, told me everything else looked good, and charged me HALF of the original quote. Seriously.
I rarely leave reviews, and I wish this didn’t sound like an ad for them, but this was the best experience I’ve ever had with an auto mechanic. Give them a shot if you’re anywhere near Orange.

I was referred to this place years ago n I never left since. I don’t trust nobody else with my car n my wife car n my friends car. This is the best place. The don’t cut corners. They will fix your car to the best of there ability and if it is time to get rid of it they will let u know. Best crew on oc. Truthful n honest.

I was referred to this auto repair business by my wife’s coworker. She said she had been going to them for years and was extremely happy. So I thought I’d give them a try and I was very satisfied with the service. They did my front and back brakes on my 2000 4WD Tahoe. The work was described clearly to me and the quote clear also.
The final cost was slightly higher then the quote but I knew ahead of time that it might be as they indicated the back rotors may need to be replaced if they could not be smoothed out. But to keep the cost down they charged me their cost for the back rotors. Your don’t hear of many auto repair places doing that for big ticket items.
Anyhow, I would definitely give Duncan’s a try as they are fast, reliable and honest and offer good value in their service.

They are the best ! Greg is so thorough, honest and has so much integrity. Plus a very nice guy. Don’t even hesitate … Go to Duncan’s !
