Eric and Company are a first class operation! They get it right the first time in every time! They will pick me up and drop me off to make it 100 times more convenient. They treat me like family and look after my best interest not just their bottom line! These are the kind of people that I value doing business with

WOW!! An amazing experience! Traveled here from Kansas to apartment shop for my daughter who is relocating and my husband was unable to join A part was dragging under the car so we popped in to see if they could help. They were so kind and helpful. Restored my faith in this world. Good people do exist!!

Eric was amazingly helpful to work with. Great communication around the whole process. He was great about calling out things that could be done without being pushy about doing them. Would highly recommend!

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

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.

Graham is great. Kept me informed of my repairs and provided an accurate quote. Pleased with the results. Walked away feeling this place is trustworthy and does quality work. Found them through nextdoor app and now I see why they have such great reviews.

I know for me one hard thing about choosing a mechanic is brushing off all previous notions I have about mechanics Potentially not treating my car how they would treat their own car. This place has done more than exceed my expectations. I got a phone call for every update, I got a thorough description of what was to be done and what was wrong, not only that, but where the dealership said it would take them two weeks to fix my car, these guys did it in less than 24 hours. I have never been happier to spend $300 in my life. Anything I need in the future, you can be sure I’ll bring it here.

Good, honest, and fair shop. If you are in sandy spring, I would not go anywhere else. Family owned and operated - take care of their customers and their crew it seems. 6 stars

Had experienced front tire damage hitting metal debris on I-285 just before Rosewll exit. Immediately exited on Roswell and saw NAPA sign and pulled in. Place was busy! But got attention immediately by Jeff service worker. Got tire off my car no waiting. Wow! Determined rim bent but tire still good. He could have sold me a new tire and i would have not known better. So appreciative. Then met with Eric McCullough and quickly arranged to have rim fixed. I decided on new tires for safety and were worn. Eric got me great deal on tires and had my car fixed SAME day. Eric runs a super customer-focused operation. Kudos! Bruce Fike

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!

Honest experts . affordable compared to other places . Only place that was willing to work on my subaru head gasket and other axle work from maybe 5 places I went to .

They diagnosed and repaired my car in time for my trip. Car works great! Eric provides excellent customer service even when he's got a ton on his plate.

I have recommended McCullough's several times to my neighbors in the neighborhood blog. I have used this company for many years and they are always helpful. It is great to have a garage you can trust.

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.

I have used McCullough for maintenance on my prior vehicle and received great service. Recently I had to repair my front bumper - I received an estimate for repair services that was reasonable. The estimated turn around time was less days than other auto shops. The best part was, the staff (Graham) was accommodating with my schedule and the repair was completed as expected/on time. The work completed was great. I absolutely recommended McCullough for auto care services.

I have known Eric and the facility for over 30 years. The service from both a customer and repair stand point is excellent. You can expect to be treated with a high level of professional performance, and courtesy.
January 23, 2020
Very respectful, honest, and professional. I was having issues with my headlights, and they fixed it for a reasonable price. They do a lot to ensure that you have a positive experience, and that you're not wasting your money on unnecessary parts or repairs. Top notch service, A+!

I received great service from this location! I called them about replacing a serpentine belt and they got it done for me the very next morning. It was quick, and cheaper than some other places that I had called for the same service. Eric and his team did a great job, and they were very nice! I will definitely return for any other auto repair I may need in the future.

My vehicle was on the verge of breaking down while I was in Sandy Springs for work last week (I live in a different town), and my boyfriend had determined that it was a problem with the alternator. He helped me find McCulloch Auto Care, which was right down the street. We'd noticed the good reviews, and we took a chance! The staff is super friendly, professional, and kind. They were able to confirm our suspicions about my car's specific issues, and took us as soon as they could. I was so impressed with their customer service. They really went above and beyond to meet my repair needs, had a fair price, and worked quickly to repair the issue. I almost wish I lived closer just so that I could have my car serviced here more often! Great family owned business.
February 15, 2021
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 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.

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.

What Can Cause A Check Engine Light To Be On?
Here are a few reasons why the check engine light may be on in your GMC.
- Worn Out Spark Plugs. Spark plugs create the spark that ignites the mixture of fuel and air to create combustion and power your engine. Dull or worn-out spark plugs can misfire, which could cause your check engine light to turn on.
- Loose or Faulty Gas Cap. That’s right. something as simple as a loose gas cap can cause your check engine light to turn on. This can cause you to lose fuel from evaporation and is an easy fix to make.
- Issues with Your Catalytic Convertor. The catalytic converter changes carbon monoxide into carbon dioxide. When your catalytic converter isn’t working properly, you’ll experience a loss in fuel economy and performance. There are many possible causes for a failing catalytic converter, all of which can cause the check engine light in your GMC to turn on.
- Failing Mass Airflow Sensor. The mass airflow sensor is responsible for determining how much air should enter your engine. Issues with your engine will occur when your MAF (Mass Air Flow sensor) is not calculating air intake properly. This can cause your check engine light to turn on.
If your check engine light is flashing, that means you have a serious problem. If it’s on but not flashing, there is still an issue, but not as severe. In either case, we urge you to bring your GMC into our shop when the light becomes illuminated. Our ACE-Certified Technicians can perform a check engine light diagnostic on your GMC to find the root cause of the issue and make repairs as needed.

Have you ever experienced a rough-running engine or felt your vehicle losing power? This may be due to an engine misfire. An engine misfire occurs when one or more cylinders fail to ignite properly during combustion. This issue can significantly impact your vehicle’s performance and should be handled promptly to prevent further damage.
The engine air filter in your car keeps dirt and debris from entering your engine. Much like you, your engine needs clean air to function. A clogged air filter can cause your engine to work harder than it needs to.
