Reviews
Trusted by Subaru owners for quality parts, expert service, and reliable performance upgrades all in one place.Very knowledgeable shop who performed a pre-purchase inspection for a car I was looking at half-way across the country.
Dominic and crew went above and beyond to help! I was in town for the holidays and I called and they helped troubleshoot over the phone. Then I brought the car in and the customer service excelled as well in person!
Very cool people at SSI. I could talk to Dom all day about Subarus. They prize only the best quality parts and craftsmanship, everything you want when you’re talking cars.I feel confident dropping off my baby.
SSI is top-notch! The owner, Rick, is a stand-up guy who made me feel welcome and took excellent care diagnosing the issues with my 2002 WRX.
