Our Company uses G&S. I LOVE THESE GUYS! VERY POLITE, HELPFUL AND HONEST! Will be taking my personal vehicle to them.

I have a 67 Camaro with 3” exhaust that needed a set of mufflers installed along with custom bent rear pipes. They were bent, installed and all of the hangers were redone to make it better and prevent rattling. The work was done quickly and with high quality. I would highly recommend this shop.... More

Stacey and his team did an amazing job on my Range Rover. It’s a 2016 and the headlights had rock chip damage. They pulled my bumper and headlight assemblies and replaced them with new ones. Charged me a cheap price for the amount of work involved. Amazing group of honest people. It’s very hard to find that in the automotive industry.

This place was great. I came in without an appointment. Had them diagnose a bad rattle coming from my engine compartment. They put it on a lift, took out the skid plate and found a broken heat shield. They welded it back up and charged me less than $100. I live in Buckhead, this would have been $500 minimum here.

I authorized them to do the work with the understanding that they had correctly diagnosed the issue. However, after they did the work they called me and said it did not fix the issue. The communication was misleading. It seemed like a bait and switch to me. I only agreed to the $250 under the condition that would fix the problem. They wouldn't budge! So I had to pay that to get my car back! Another shop easily determined i had an ignition coil problem, and made a quick, cost efficient repair that solved the problem. I understand these diagnostics can be tricky, but do not tell me you found the problem and then charge me and later tell me "oh we were wrong but you still have to pay". Less

My mouth dropped and my interest was piqued. I called, spoke to Stacey, and he asked how soon I could bring it for him to inspect. The dealership quoted me a $500 rotor and brake job. Stacey’s team found that I didn’t need rotors and that my pads were good, just in the wrong place. They machined the rotors, “scuffed” the pads, and placed them in position. An hour later the repair was done and it was no where near what the dealership tried to rip me off for. Blessings to G&S and its staff! Much appreciation to them all, especially Stacey!!! Less

My 19yo is in Georgia for a few months, and their car developed an exhaust leak that gradually got louder and louder. A shop nearby said they don't do a lot of exhaust work and recommended G&S (Marietta). Stacy @ G&S was very polite & professional, didn't bat an eye when my kid wanted dad on speakerphone to talk about the diagnosis & estimate. They got the car in the next morning and completed the repair the same day, quickly, correctly, for the quoted price. My kid drove away, circled the block and came back because the check engine light came on, and the car was still loud. Stacy went for a ride with them and instantly diagnosed a bad wheel bearing (that noise had been masked by the exhaust leak); he pulled the codes (bad oxygen sensor) and confirmed the code by testing the sensor itself. The car is 16 years old and the sensor was probably on the verge of failing, and vibration from the exhaust work just pushed it over the edge. On speakerphone again, polite, professional; we talked through it and agreed that the wheel bearing is a safety issue that had to be fixed before driving back to Pennsylvania in April; we agreed the O2 sensor is not a safety issue and can wait, and we'll change that out at home. He didn't charge anything for diagnosis time; my kid brought the car back in the next morning to change out the bearing, again done quickly, correctly and for the agreed price, and is now amazed at just how quiet the car is.

Took it back to them today, and was told that I had bad tires and the tire rotation was causing my problem… left there and went to another alignment shop in the area… they quickly found the issue. G&S hadn’t righted the steering alignment nut, and had been working its way loose! Could have been disastrous! What bothered me the most was the insistence that it was the “tires” that caused the issue, without taking 5 seconds to check out the problem! Less

Was recommended to go to C&S muffler to have my off road x-pipe and axle back track exhaust installed on my 2015 Z06 by a service manager at Steve Rayman Chevrolet. I called Stacey that Thursday and he got me right in today( Friday)at 8am sharp. From the time I arrived until the time my vehicle was completed, it was a pleasure sitting there talking. I’ve owned plenty of vehicles and this was by far the best service experience I’ve ever had. The hospitality, the attention to detail, the great prices, and just the overall experience was outstanding. While being there, I realized this was pretty much a one stop shop that does way more than what I thought. I have four other vehicles and will not take them any other place except here. If you haven’t been by this shop off Lower Roswell rd for auto service, you are truly missing out. I don’t usually rave about places too much, but this shop made a believer out of me. Stacey, I want to personally thank you and your outstanding shop personnel for the great environment you have created. You now have a customer for life. See you soon for something else. Less

Great price on brakes for my car, work was done great as well

Good job 👍

The Best There Is.

Stacy and the guys are great and tight work on my Flow Master cat back exhaust on my 2020 Silverado 1500.

Excellent place to get alignments done.

Stacy is the man, great service great prices, the most honest shop in Marietta

The AAA service technician broke 2 of the studs while replacing my flat tire with a spare.

I purchased a new tire, but they couldn't take the spare off because of the broken studs so they suggested I call G&S Auto to have them replace it, much better deal than taking it to the dealership. Sure enough, the price they quoted me was $230 less than Curry Honda! I drove up to G&S, told just called about the studs and Stacy let me know he could have me out of there in about an hour and that is exactly what happened! Great service and incredible pricing!!!

I never have to worry when I bring any of my cars to G&S. Timely, professional and friendly! I love coming here!

Quick and efficient. Thanks Jeffrey

Not sure how good of a service this will be since they don't know how to book appointments and be accountable. Was denied service at the appointment time of 12 noon. If you desperately need service done and you live closer than 20 minutes away, maybe risk it and take a chance on these guys.... More

Best shop in town hands down. Stop looking and go experience the outstanding place for yourself.

Great service!!! Love the way my new truck sounds! Thanks to all the guys at G & S

Fantastic. My new go to mechanic

Knowledgeable trustworthy staff, fair prices, efficient timely service. This will be my go to place to service my car.

If you need muffler or exhaust work done on your car this is the right place and with good prices

This was the worst service ever went to get 4 studs put in took 2hours and even messed up my rims theses people are very 🐌 slow.

The work was good as far as I can tell.

I have frequented G&S in Marietta for all of my automotive repair needs for years, and feel a bit guilty not having yet left them a review.

I have frequented G&S in Marietta for all of my automotive repair needs for years, and feel a bit guilty not having yet left them a review. They're honest, highly competent, and charge fair prices for the work they perform. I especially like G&S because they don't mind a customer bringing in their own parts - they just won't warranty your carry in parts - which is understandable. They also aren't afraid of installing aftermarket or high performance parts either. That said, they also charge very fair prices for parts that they source themselves. I won't go to any other G&S but the one in Marietta, and I've tried them all. Less

An honest and hardworking mechanic. What else do you need?

A mechanic you can trust no matter the situation!

Not much to say, they were very helpful and got right to work. They don't speak much, but they get work done and get it done fast.

Great prices, very friendly and made my truck sound awesome in less than a hour... I'd recommend this shop to a friend definitely...

Excellent service! I had a crack in an exhaust pipe. Two different mechanics gave me a quote of $1,200+ to fix it due to the converter being attached to the eroded pipe. G&S fixed it by, instead of replacing the pipe, cutting out the bad section and welding in a replacement. The cost was less than 1/10 of the quotes from the mechanics. Thank you G&S!... More
