High performance modification service near Redmond, WA

Al has been fixing various issues with my wife's Audi for years. He's great at communicating what's going on, typically over estimates and charges less, and often fixes little things and refuses to let us pay him for it. Not many businesses like this around anymore.

Love these guys!

Your customer service is wonderful. It's important that I feel I can trust who I take my car to & I trust ZahnTech. I'm glad I found you.

I found the staff to be Audi experts and enthusiasts. I really appreciate that they went above and beyond to fix the car correctly, and communicated with me each step of the way. would highly recommend!

I really like these guys. They really know what they are doing and unlike a lot of mechanics seem to really actually care about the quality of their work through their attention to detail and communication with the customer. I had them bring my car back to life which was neglected for a long time by me and I was surprised to they were able to actually fix all the issues for a very reasonable price. I feel like I can trust these guys which is all to often not how I feel when I have been to mechanics in the past over the years. Thanks Rali-Round, keep up the good work! Jason Elkins

Sometimes things happen. It's how a business handles those things that matters. My daughter had her car repaired at the garage. Four days later the new part failed causing other problems. Bob had the car towed to his garage from quite a distance, reviewed the problem and repaired the vehicle. It is running great now. Bob was very professional and stands behind his work. I highly recommend him and this garage. Thank you, Bob, for all your concern and help.

Monte did a quick check, told me the exact price. Installed to new Coils & Spark Plug Assemblies. The Speed Sensor Checked out okay so he reset the Check Engine Light. He gave me an exact quote before he started the work. He got the work done quickly and I paid him. He came to my location. Now my V-10 is purring like a kitten. Monte is completely competent, his prices of very compettive and will definitely use him again. I have already recommended him to two of my friends with RV's. I give Monte 6 Stars!

We hired Bryan to come out and install a fuel pump in our Classic 57 Chevy in early July. He promptly came out,,,,,,without calling. We had the fuel pump and my hubby (who is 80 and legally blind) had taken the old one out. We just needed Bryan to put the new one in. He did this. He hooked up the gas lines, we paid him and he left. 2 days later we went to take the car out and the gas lines were leaking badly. We contacted Bryan,,,,,,he said he was hired to install a fuel pump not hook up gas lines..????? We have been in touch for nearly a month now,,,,,he had a family emergency, he has to check his schedule, etc ,,,,,and now he won't even reply. I do NOT recommend this guy if you want a guarantee on his work.
