Guaranteed Automotive & Transmission Service was founded in 1983. Second-generation owner, Clint Johnson, essentially grew up in the business, and his mom (and co-owner) Terri still plays an active role in the operation. We’re a family business, and that means we treat our customers as family as well. When you trust your Mercedes to our ASE-Certified auto mechanics, you can rest assured that we won’t recommend any unnecessary car repairs.

Mercedes car repair requires specific training, diagnostic equipment, and tools. They’re sophisticated vehicles and our auto mechanics actively train and study the evolving technology of this leading-edge automobile brand. That’s why we have built up a loyal customer base of Mercedes-Benz owners since we opened in 1983. Read what a recent customer had to say about his experience with us:

“This was a much better experience than most that I have had. The people were friendly and showed me directly what was wrong with my vehicle. The price ended up being right around where I figured that it would be and the waiting area was a nice, cozy place to kick back for a few hours. There were even fresh snickerdoodle cookies on the day that I had my transmission worked on. I'd definitely refer them to anyone in the area who needs transmission work done.”
-- Jacob I.
