Professionalism & Quality in Auto Diagnostics

Behind the wheel of any type of vehicle— a convertible, a sedan or a heavy-duty truck— you probably know yours well enough to recognize when something’s not working correctly. This is when auto diagnostics will uncover the exact problem and lead to the solution. At the same time, you want the peace of mind in knowing the diagnostic results are correct. Therefore it’s important to find the shop you can trust to do the job thoroughly. That shop is Greg’s Champion Auto in Mankato, MN, where our team proudly exudes professionalism and quality in caring for every vehicle before us. Auto diagnostics are a part of ownership, and we’ll make sure you’re driving at your best!

Intelligent Decisions Beyond Auto Diagnostics

Here at Greg’s Champion Auto, we’ll efficiently diagnose any issues with your vehicle, foreign or domestic. That’s just the beginning. In addition to immediate auto diagnostics, you’ll get a long-range vehicle health plan based on the results of our digital inspection. This includes photos of all parts in their current condition. Perhaps there’s a small leak to monitor, your tire tread is wearing down, or your fluids are getting dirty. In any case, you’ll have the information beyond auto diagnostics to make intelligent repair decisions based on what’s most urgent and what can wait. Many shops will fix your car or truck, but Greg’s Champion Auto is here to take excellent care of you and your family.

Great service! The staff were wonderful to talk to, I had multiple issues that made the problem difficult to diagnose. Their mechanics did a great job finding and solving the issue with my brakes and were able to explain everything they had to do. They also offered me a loaner vehicle while they had mine at no cost. Very happy customer and will definitely continue taking my vehicles here.
