Performance Vehicles

Took my CTS-V in for some performance work. Very affordable and easy to deal with. Will be coming back next time I need work.

Andy H.

Stuart is a top class technician and an honest guy. I would not hesitate to send any of my friends or family to SL Autoworks.

Danny W.

SL Autoworks is THE place to take your vehicle. Stuart is very good at what he does because he is super knowledgeable and trustworthy! Highly recommended! Your vehicle couldn’t be in better hands. Great experience with this business and I will definitely be returning in the future!

Kacy B.

Just got my car back from here. He went over everything installed and recommended purchasing additional parts for the future build of my car. I asked him about other services that I thought were needed but was advised against it at this time due to it not being necessary. Gave me a great price on the parts and installation. Definitely going back to him for all my vehicles not just my Subaru!

Joshua S.

I have only gone to SL Autoworks since buying my 08 Subaru Impreza STI. Stuart's attention to detail and honest work ethic is what I seek out in an auto shop! I only trust him and Forrest working on my vehicles.

Brittany C.

Stuart is the guy to see if you need anything. I destroyed my clutch in one of my cars and was having trouble finding a replacement that would hold up to the abuse my OEM couldn’t. I messaged Stuart later than anyone should have and first thing I woke up to was a message saying he had just the part in mind. He placed the order for my new ACT Heavy Duty clutch within minutes of confirming it was the correct route. 3 business days later and I have a brand new clutch that I won’t have to worry about killing! Undoubtably the best service I’ve ever received from an automotive shop. Definitely going back to SL Autoworks for parts and guidance!
