Upon inspection of your vehicle, we always give free auto repair and parts estimates and provide options to work within your timeline and budget.


When you bring your car to our shop for servicing, you don’t always have time to wait for it. To keep your busy life going, we offer free local pick-up and drop-off services.


Oftentimes customers only have access to one vechicle, and when it’s in our shop, we’ll send you home with a loaner so you can go about your life.


Leave your vehicle for repair even if the shop is closed. Just put your keys in our drop-off box and we’ll call you when it’s ready!


The ACDelco Consumer Assurance program delivers roadside assistance and a nationwide 24-month/24,000-mile limited parts and labor warranty. We also accept extended warranties.


About Us

Deutmeyer Auto Advantage has been a family-owned and operated full-service mechanic shop since 1981. We provide motorists in the Dyersville area with comprehensive and quality auto repair services on both domestic and import vehicles as well as trailers. We combine our expertise and the latest technology to assess your situation and offer you options. We treat our customers like family with a personal obligation to each one, and we guarantee you'll be happy with our service.

We’ve justly earned a reputation for providing unprecedented honest, high-quality sales and service at a fair price. We know that trust is a major factor in the relationship between the services/sales facility and the vehicle owner, and we strive to earn the trust and respect of our customers each and every day.

Owner Mike Deutmeyer has specialized in the service of automobiles since 1981. His breadth of knowledge in mechanics and the auto business carries over to his team of highly trained and certified technicians who are able to service complex vehicle systems of all makes, models, and ages.

We are sometimes asked what makes us different or a better choice to other service facilities. Simply put, we provide the overall lowest cost in auto service without sacrificing quality. We do this by preventing problems, not just repairing them. We care about YOU and your vehicle, and we don’t just say that, we measure it.

Our Shop

Our new facility was built and opened in 2017. It was designed to maximize efficiency and is packed with the latest electronics and technology in the auto industry. Our lobby is centered around our customers and provides a clean and comfortable environment to watch television or read magazines while enjoying complimentary coffee, soda and candy. Of course, if you don’t want to stick around and wait while we service your vehicle, you can always take a courtesy car home!

Best car guy ever. Mike does good work in a reasonable time for a reasonable price. He goes that extra mile to find the right part. He's always courteous. Been going there twenty years and the service is always great. This is the dependable garage you always hoped you'd find.

I had a repair needed done asap. They not only gave me a price that was half of what Midas wanted they had me back on the road sooner than I thought. Outstanding hospitality and professional service. I would recommend this business to anyone and all.
