Sumners Automotive: A Legacy of Hard Work and Quality Service

Sumners Automotive is a local, family-owned and operated auto repair shop in Rapid City, SD, founded by brothers Aaron and Andy Sumners. Their commitment to hard work and fixing what's broken was instilled by their father, Bill Sumners.

ο»Ώ

Aaron, a Master ASE certified technician, developed a passion for cars and gained a decade of experience in the automotive industry before he and Andy (who specializes in welding and fabrication at their co-located business, Elite Fabz & Design) launched their dream of owning their own shop toward the end of 2020. Despite facing the immense personal challenge of losing his wife to COVID-19 around the time of their launch, the business has thrived thanks to the resilience of the owners and their dedicated crew.

"Out for vacation from MI, we had a trailer / rear suspension problem after a small accident on I-90. They (Austin) got us in, and gave us options to correct rear suspension. In and out the tech was awesome, great communication and even better listening skills and interaction especially with being out of town / state. Great Customer Service good prices."

5-star review by Patrick Sempert

"Over the past two years Sumners Automotive has become my go to shop for a variety of services. Several different types of critical fluids (differential, transmission, coolant) were due for replacement recently in my Dodge Challenger and the great crew at Sumners got them drained and refilled very quickly and efficiently. I also saved about $700 compared to what the local dealership would have charged me for the exact same services."

5-star review by Nick Mashek

"I went to the shop for some expected maintenance and have an overall check on my 170,000 mile vehicle. I was worried about a couple things and they told me that nothing was in bad shape. The honesty to not replace a part just cause the customer brought it up is great. I won't go anywhere else now."

5-star review by Philip Coon

"Very satisfied! We showed up with our old van with a large coolant leakage and they could schedule us in immediately! Top personal service. They definitely went above and beyond and got us back on the road, even this was a very difficult job! Very honest people too! Can absolutely recommend! πŸ‘"
