I've taken my STi here 3 times now and had no issues. It is the only shop I trust with it. They always keep me updated, the work gets done when they say it will, and the price is exactly what is quoted. I definitely recommend them.

All the guys here are super knowledgeable and trustworthy. IMO best place in NH to bring your Subaru if you need some work done. Over the past few years i’ve brought multiple Subaru’s here and have never been disappointed.
