We are one of the leading auto repair shops serving customers in the Lake Country area.
All services are performed by highly qualified, certified & experienced auto body technicians.


When you get auto body work done at our facility, you can rest assured it’s top quality. We don’t believe in performing rushed repairs to meet a deadline or cutting corners to save money.


We have auto body technicians specializing in every aspect of collision repair and car maintenance, including our ASE Certification and our I-CAR Gold shop at our Sussex location. Our technicians all have a personal reputation for outstanding work.


We are a preferred auto body shop for most major insurance companies because we make filing claims as simple as possible, including working directly with providers to accelerate the process.


We are much more than a typical auto body shop.  We offer a complete range of services including smaller jobs like vehicle buffing, complete paint jobs and painted pinstripes.

  • Collision Repair
  • Hail Repair
  • Glass Repair

  • "This is the greatest group of mechanical gurus I have met in a long time. I tend to have goofy things happen in my driveway and Mike and the rest of the guys make life easier after a visit to them. They are nice, personal and professional. They are efficient, friendly and helpful. My vehicles are grateful they are there!"

    Angela B. Hartland, WI
  • "I can't say enough about Mike Parve and the rest of the crew at Merton Auto Body. They took care of me and my Lexus like true professionals. Mike always kept me updated with the progress and the team finished a few days earlier than anticipated. Despite having my car in an accident, they made the experience tolerable because of their great service. Kudos to Mike, Brian, and Ryan. You earned my business."

    Don E. Sussex, WI

Merton Auto Body

We Bring Broken Windshields, Crunched Fenders, and Dented Doors Back to Life

An accident doesn’t just damage your vehicle, it can turn your life upside down. Let Merton Auto Body, the leading auto body and repair shop with 2 locations in Sussex and Oconomowoc, restore your vehicle (and your peace of mind). We have the people, tools, and parts to get the job done according to manufacturer standards and yours.


From a Small Garage to the Leading Auto Body Shops in Sussex and Oconomowoc

Founded in 1946 by John Rellatz, Merton Auto body was once confined in just a small garage in downtown Merton. Around 30 years later, the company was passed on to his son, Ron, where the business was relocated to a bigger building and hired Paul Shiellack and Steve Anderson. The two soon purchased the shop in 1995, and in 2014, Ryan Carriveau took over the operations.  In 2021, we acquired Radix Auto Body. Today, we’re the leading auto body shop in Waukesha County, with 2 state-of-the-art facilities that meet the demands of customers and their increasingly complex vehicles.


Certified Professional Auto Body Repair Specialists

We are known for our top-notch professional auto body professionals. From the repair specialists and painters to the estimators, our Sussex location has I-CAR Gold Trained technicians, with additional certification from the National Institute for Automotive Service Excellence. We work as a team to accurately assess the damage and do the necessary repairs, so you can get back on the road as soon as possible.


Comprehensive Auto Services

Other than collision repair, we also offer a range of other auto body services in Sussex and the surrounding Lake Country area, including hail repair, glass repair and replacement, and paintless dent repairs. We also provide detailing, buffing, painting, rust-proofing, and wheel alignments.

    ASE exams are not easy. Only two out of every three test-takers pass on their first attempt. To remain ASE certified professionals, we’re retested every five years to keep up with the ever advancing automotive technology.
