I would like to say thankyou to everyone for continuing to support MSR. Being a one-man show, I can be quite busy at times! None the less, I aim to provide quality, trouble-free motoring to many Subaru owners. If you have any questions or want to have some work done to your vehicle, please do not hesitate to contact me by submitting an enquiry and I will get back to you as soon as possible. Stay tuned here and follow MSR on Facebook for the latest news and offers!
