Testimonials
What our customers say about us
We’re proud of the long-term relationships we’ve built with European car owners across Oregon. Their words say more about our standards than we ever could.

I have been taking my Porsche Cayenne to Matrix for regular maintenance for the past 3 years. I’m impressed with their service and especially with my most recent customer care service. They noticed that my DEF fluid pump seemed to be leaking. Instead of recommending that they fix it for me, they shared that it was most likely still under recall warranty and to call our local Porsche service company to get it fixed under the warranty program instead. This saved me thousands of dollars.

Beth Melner. Porsche Cayenne owner

I had a request for an in person interview 300 miles away when an EPC and Check Engine light kicked on in my GTI, on my birthday of all days. If you don’t know, that’s a big problem in a GTI. To make matters worse I was preparing to move. The team at Matrix not only checked my car right away, but let me leave it with them to see if they could squeeze it in. They not only got it done a week before their next appointment opening, they only charged me for parts and one hour of labor. No rush fee. No extras. I’ve never seen someone step up and go above and beyond like that. Seriously if I want to do anything major I may drive the 300 miles to come back as I know it’ll get done fast, fair, and right. They also have a really cute loaner car up front 😎

Had some upgrades for my Sprinter done here. Worked with Jeremy, he’s one of the owners and soooo knowledgeable and passionate about Sprinters and European cars. He’s the real deal! I’m from out-of-town, they picked me up and dropped me off at my hotel while the work was being done. They were 100% on their predicted timeline. I am very happy with everything they did. Looking forward to my next project. I had flares installed above my wheels, blacked out Mercedes emblem (so cool!), Sherpa rack system and ladder installed plus two large expedition boxes.

Carl O’Neil. Mercedes Sprinter owner

Came in with a blown turbo on my beloved 2013 335is – Christian and crew worked with me to a get a reasonable price with full warranty and replaced the turbos. Car is running like new. Would highly recommend

Kyle Steen. BMW 335is owner

I’ve been bringing my Audi S4 to Matrix for years, and it’s truly been a pleasure every time. The team is always kind, friendly, and professional. They do exactly what they say they’re going to do, and they do it quickly — no surprises, no runaround.

The prices are always fair, and the quality of the work is top-notch. I also really appreciate how convenient and well-kept their workspace is — it just makes the whole experience easy and comfortable. It’s rare to find a shop that you actually enjoy visiting, but Matrix has earned that trust. Highly recommend!

Andy Arthur. Audi S4 owner

Prompt service and fair price. I’ve taken my Land Rover here at least years in a row for maintenance & service and always been pleased with them. Highly recommend to others.

Jan Sweeny

Excellent job fixing my Porsche Macan S. Great communication! Assisted with my extended warranty company, and exceeded expectations overall. I will be back … but hopefully not for awhile!
