I made an appointment and Ashley, I apologize if I remember her name wrong, welcomed me. I'm handicapped and too short to get into my sister-in-law's truck as I forgot my portable step. Ashley brought out a tire rim they used for a step stool and it worked perfectly! She even let us take it with us so we could do errands while they did maintenance on the van. She called and gave me an update on the work and also called to let me know they were done. This shop is the best! They've helped my sister-in-law with two issues on her truck at the last minute and still got her in and diagnosed the problem.

Let's face it. You NEVER want to have to take your car to the shop for an auto repair. But when you…read moredo, I recommend this place. They know what they're doing and do a great job with great service. Sometimes they get busy, so if it's something that can wait, call ahead and make an appointment.

If I could do 6/5 stars I would honestly. After putting a hole in my tire at 4 am on my way to work…read moremy day was not going well. I called up here and spoke to Daniel, he was extremely informative, super nice, asked questions to make sure I was getting the correct type of tire for my drive style, and more. Daniel and Dwayne were both extremely nice, informative, and explained everything. They didn't try to push the most expensive or extra stuff I didn't need, exactly what I needed, recommended something else and I ended up getting it cause it would help my car in the long run. I got all 4 tires replaced and an alignment. Also they let me bring my dog which is huge for us cause he has horrible separation anxiety. Seriously, 11/10 would recommend to anyone, super fast, reliable, explained everything, and prices were reasonable with market value.

I was traveling through the Deadwood area in my RV when I started loosing pressure in one tire. Les…read moreSchwab was able to get me in right away the next morning and check it out. They found that the leak wasn't the tire but the valve extender had been rubbing on the wheel cover and caused a hole. They were able to put a new valve extender on and send me on my way. They didn't even charge me for the visit! I stopped at the Les Schwab in Mitchell to get a re-torque on the lug nuts. When I pulled up into the parking lot a guy from the garage stall he was working in literally came running out to see how he could help. He did the re-torque, no charge once again, and sent me on my way. That is good service at both places.

When presented with the bill, they told me they had to add an additional half quart to my Mercury auto which usually takes 5 quarts. Their charge was an additional $4.48 for the half quart.

We stopped into Exhaust Pros to see if they might be able to squeeze us in, but they were fully booked and all their lifts were actively being used. They went above and beyond to find a shop that could get us in and that they felt they could recommend. They did not have to help, but they did and I am sure they would have done a great job if they had been able to.

On one occasion, I sent my parents who were in from out of town to have a few items checked and mechanics were patient, accommodating and recommended no needed fixes after looking over their concerns. On another occasion, they fixed an issue we had been to two other shops on, and finally got the problem diagnosed and corrected. These guys are smart and honest. We are grateful to have them to go to!

A dealer in Wyoming took it apart because of valve train noise, but found nothing wrong. Dakota V-Twin put it back together for us, fixed the noise it was originally torn down to find, and charged us one third of the dealer's quote even though their tech worked on it until 9:30 on Sunday night to finish it so my wife could ride the Black Hills! This kind of service and dedication are unheard of! I can't speak highly enough of Dakota V-Twin, and highly recommend them to anyone who needs parts, service, or repairs.
