I’ve been bringing my cars to GSS since 2022, starting with my Porsche Panamera Turbo, followed by my Audi R8, and now my 991.2 GT3. Every time, their team has provided outstanding service with expert craftsmanship and attention to detail. Most recently, I had my PDK transmission and Final Drive serviced, along with an oil change, summer tire installation, and an exhaust modification. The work was done with precision, and the GT3 now drives flawlessly—smooth, responsive, and exactly as it should be. GSS has always been my go-to shop for both routine maintenance and performance upgrades. Their professionalism and deep understanding of high-performance cars set them apart. If you’re looking for a trustworthy and skilled shop, I highly recommend GSS! Big thanks to the Elie, Dion and entire team for their excellent work!

I have used GSS on several occasions and their service has been excellent from every employee I came in contact with. From simply getting my oil changed to having major engine work, I have found them honest & their workmanship top notch. Even getting gas there is a pleasant experience. Since I began bringing my car here, it has ran better than it had in years. I was considering trading it in as it was getting older, however it runs so good now I am happy to keep it. If you are looking for a new shop in the Newton or Watertown area, I would definitely recommend giving them a try. Their customer service is A+!

I get gas here a lot, have never done anything else there before. Very friendly, and quick but thorough service. I got my inspection, oil change and new wipers--which I really did need--done in under an hour on a random Monday. I know they filled my tires because I checked the pressure before I left the house, I thought I had a leak and would've bought a new tire too. No leak, but each tire had a slightly off number. I checked the pressure again after service and all the tires were filled to the same level. It wasn't just a line on the invoice. I appreciate these people very much!

Since 2021, all my car maintenance and parts replacements have been done at GSS. Every time I’ve had an issue, Elie & Dion have always gone above and beyond to help me. This time, during my inspection and when I had a problem with my wheels, they did everything they could to resolve the issues, they also offered me the best price, allowing me to enjoy top-notch service while saving money. Moreover, their car detailing service was truly impressive. They gave me a free car wash and when I picked up my car, I was amazed—it looked as though I had just purchased it. I think I will addicted to car wash after this time. Even though I’ve moved to Quincy, I’d rather drive 40 minutes to get here because I can’t think of a better place than them.
