WHAT OUR CUSTOMERS SAY

I have used js automotive years ago for my girlfriends car, and they treated us very well. They even went as far as giving us a shop vehicle to use for 2 days, while our car was being worked on, and waiting for parts. I went back last week with my new to me 2015 Chevy Silverado. Unfortunately ended up needing a new transmission. These guys treated me very well. Got the transmission for me, and had it in within a couple days. They did a very professional job and kept me updated along the way. The transmission work wasn't cheap, but quality service never is cheap. I won't bring my truck anywhere else. Thanks again Ryan and the crew down at J&S automotive in Charlestown. , 10/11/2024
