Testimonials

On 10/16/2025 Tom Knight had this to say:
On our way to Colorado my F150 lost power on I-80 at 4:00 pm. Called a Ford dealership in the area and they were about to close for the day. They recommended Andy’s Auto. We called Andy’s from the side of the road around 4:30. With a tow truck on the way Karen and the team waited for us. We rolled in around 5:45. The team took a look and ordered a fuel pump and related parts for the morning. They fixed everything up as soon as the parts arrived and we were on the road by 3:00 the following day! Incredible next day service! They even recommended a hotel down the street and saved us some money there too! Really an excellent experience. We highly recommended Andy’s Auto!

I was traveling from Chicago to Colorado recently and discovered that the undercarriage cover on my vehicle was hanging about ready to fall off. Stopped in at Andy's was immediately seen and taken care of. To my surprise there was no charge to have them resecure the cover. Andy's Auto truly knows the meaning of Customer Service which is something that other companies only pay lip service to. Thank You for helping me out and getting me back on the road.

On 8/27/2025 Mollie O'Dell had this to say:
So thankful for the Andy’s Auto team! They took on a hard fix that many didn’t want to do and got everything running so smooth again. Even took the time to show and explain what happened and what they did to fix it. Great service!

On 7/31/2025 Russell S had this to say:
Was driving from Milwaukee to Des Moines when my front axel went bad. Got a local recommendation to go to Andy's and it was the right choice. Talked to Justin who said he could get the part about 1:30 that afternoon and the job would be about an hour and a half. I was driving away with a repaired vehicle at exactly 3pm. He realized I was stranded and was able to fit my repair in to get me back in the road. Great service! Testimonial written by Russell S on this site.

Wonderful mechanics and most kind. Would recommend them. I don't know why I need her 85 characters for review just to post it though. LOL
