This place has fantastic service times and an extremely knowledgeable staff. First time I went was for an emergency tire change and it went even more smoothly than I would have ever thought possible. Definitely recommend for any/all vehicle maintenance.

I own and automotive repair business in Jacksonville, but my wife lives in Atlanta and needed tires for her car, so I know good service and fair pricing in this industry. I chose McCullough because of their good reviews and they did not disappoint. They were very professional and took good care of my wife. I would highly recommend them and will continue to use them for her service needs.

This is the best place you could possibly go to take care of your car! My family and I have been going here for over 15 years and we recommend them to everyone. Eric, Bryan, and Graham are the most trustworthy guys and truly care about their customers. We all love them and are so thankful we found them!!

Have been going to McCollough’s for decades! Once I found them, I knew they were honest and professional. Not often one can say that about an auto repair place. They have helped me keep my older vehicles safely on the road for longer than I could imagine. I have always been treated with respect, no matter how large or small the issue, which is excellent and reassuring for an older woman.Highly recommend them!

We had an issue with a splash shield dragging and overheating. We are heading back to Kansas this afternoon. They were able to fit us in despite being super busy & do a quick fix and sent us on our way in 10 minutes. So kind and amazing service!

I was so impressed with these guys!! Family business and the guys are professional, efficient, and personable. They got my part quickly and fit me in so I could come while my kids were at school. They went the extra mile (no pun intended) to consult with another auto body shop to make sure the repair was stable. I will be coming back for all future auto needs and will recommend them widely.

After recently moving to the area, I had a vehicle emergency where my transmission needed replacing. Graham immediately took me in and was SO kind, professional, and direct about the costs; one of their kind staff members even drove me home after my car was dropped for repair so that I did not have to call a car service. They were so patient with me and got my car back to me in one day completely fixed and ready to go! I will never use any other automotive repair shop in the area! ABSOLUTELY recommend without hesitation!

This place is exactly the kind of service you come to expect. Great service, timely, and they never assume I don’t know what I’m talking about because I’m a girl.

Came in for emissions and they exceeded my expectations! Saw headlight out, replaced it. Saw no oil sticker, checked it and put a little in it until i can get back in for change. While waiting you could tell these guys really care about their customers and the safety of their vehicles. Definitely will be coming back here!

We have been depending on McCullough's at least since 1997, when we purchased a home only a few blocks away, walking distance really. Had our emissions test a few days ago and want to acknowledge Jack, who completed the tests quickly. I asked him to determine why the backup camera was not in the proper position. It took a bit of time and ingenuity to get everything right. Thanks Jack, for the excellent service.

Eric has been my service manager for years. He is always professional and easy to deal with. He goes out of his way to take care of your needs and makes accommodations to the customer when needed. They will ferry me and my car to and from their shop (I live within blocks) and I appreciate that very much. Everyone at McCullough is nice, friendly and helpful.

I found my new home for car repair. Eric was very nice and honest. We definitely be coming back! Thank you for the excellent customer service.

My parents and I have been taking our cars there since the beginning. Great, hardworking guys. The only mom and pop shop left in Sandy Springs.
January 2, 2022
I really cannot count the number of times these brothers have taken care of me, my family and all our various vehicles. We have been loyal customers for more than 20 years! They have done everything we have needed on cars, trailers, used car evaluations for purchase, tank drops, and all the basics. They are very trustworthy and will give you a honest answer on everything and a reasonable estimate on what it will cost to resolve it. They are super busy, so plan to wait a day or two longer than you might somewhere else, but it is worth it!

Eric was amazing from start to finish. I chose this shop for my repair based on previous reviews & I'm glad I did. He made sure to, in my opinion, go above and beyond with his politeness, as well as helping to make the process smooth and to try to save me as many coins as he could, while still getting done what was needed. Very happy with this visit

They figured out the issue with my Pathfinder and made the repair quickly. Eric is very thorough and kept me up to date the entire time. This was my first time using them but I will use them again!

This has to be the best shop in town! When I got my car fixed the last time, It drove live new. I've never been so happy to get my car fixed in my life. They were very friendly and honest. This will be my go to place from now on. Not too far from my house which is a huge plus but even if it were, I'd be game to making the trip. Thanks for being honest and giving great service!

I live in Brookhaven and work in Duluth and pass dozens of auto repair shops on the route. I will forever go out of my way to go to McCullough. This is hands down the best repair shop I’ve ever been to. They are honest, kind, and treat each customer with the utmost respect. I’ll never take my cars anywhere else!

I would normally recommend this business as I have been here a few times. I went there Friday for an oil change. However, I honestly didn't feel safe. They have signs that customers must wear a mask. There was only one employee wearing a mask themselves. All the others didn't have a mask on. I feel this is disrespectful to their customers. I understand it can be uncomfortable but it is essential during these times.

Always extremely professional. Willing to work with customers. Sadly, car repair is expensive but they have worked with me. Graham has been extremely helpful with issues my daughter was having with her car while we were at another mechanic in the area. We asked on Nextdoor for recommendations and McCullough came up numerous times!
May 14, 2020
Wow! I am so impressed with the service I received. Having moved here from Nashville I was nervous about finding a mechanic! These guys are BUSY but they treat every customer like their priority. I got my car repaired within two days on a weekend! Prices can’t be beat and I was getting phone calls with detailed status updates. Amazing service. Really compassionate. Please doing business! I thought I was going to have to spend thousands fixing the plate that was dragging under my car but I got it fixed for under $200! Thank you!!!

Eric and everyone at the shop is fantastic. I call and they are so kind and accommodating. No wonder they have so much business!!! Despite the amount of customers they have, they treat everyone with respect and attention. Love doing business here. Could recommend more. Fast, excellent service !! -Alexa

McCullough has been my family's go-to mechanic for decades. Don't know what I would do without them - just a super-nice family that will take care of your cars. Their service is important to us because once we get a new car, we like to hold onto it for years (10-12). Highly recommend.
December 3, 2021
This place is a life saver. Great communication, great service, and very professional people. Eric worked with me through my whole repair. Kept me updated through out the process and fixed the problem on my car at a fair price. I will definitely make this my new place to go for all my car repairs and maintenance needs, along with sending my friends their way.

Signs Your GMC Needs Engine Repair or Replacement
If you notice any of these issues when driving, you may need GMC engine repair, maintenance, or replacement. The longer you wait to service your GMC, the more in-depth maintenance may be. We’d like to encourage you to bring your GMC in for service when you first notice these signs.
1 – Check Engine Light Is On
An illuminated check engine light can indicate various issues with your GMC engine. The issue may be minor, like a faulty oxygen sensor, but failure to have the issue repaired promptly could lead to a failed catalytic converter, which is a much more in-depth fix.
2 – Decreased Performance
Do you notice that you aren’t getting as many miles to the gallon as before? This could be the result of any number of engine issues. Minor services, like replacing spark plugs or swapping fuel filters, can help restore engine performance.
3 – Fluid Leak
Leaking fluid is always a sign that something is wrong with your car. Your engine can suffer negatively from a coolant, antifreeze, or oil leak. If you notice fluid dripping from your GMC, bring it into our shop for service.
For professional GMC engine repair, maintenance, or replacement, visit McCullough NAPA Auto Care in Sandy Springs, Georgia. Our team has over 50 years of servicing GMC vehicles. Feel free to call us at (404) 252-3014 or contact us online to schedule service.

Spark plugs provide the necessary electricity to ignite the air and fuel mixture in your car’s engine. This combustion creates the energy to start your engine and power the pistons. Without healthy spark plugs, you may experience a decrease in performance and fuel economy.
