We traveled from Orlando to Wall , SD and our F250 had mechanical issues. We were 239 miles away…read morewith no repair service. In Wall , SD , the locals recommended D&F Truck and Auto. Er had called a dealer in Rapid city before someone told us about D&F. This place is a real auto mechanic shop! We had no idea what was wrong as our truck wouldn't drive past 50 miles an hour. And the owner had this truck fixed in no time. The dealerships before someone told us about DF told us that repair will take weeks. And this shop fixed it in less than 4 hours and it was perfect. I can't thank the locals for this recommendation. A very honest shop that didn't gauge us with $$$$. Rapid city dealership didn't care. But D&F truck and auto repair in Wall , South Dakota did such a wonderful job. Fixing our truck and off we went and enjoyed our vacation immensely. Thank you D&F. You did such a wonderful job and we appreciate your patience and troubleshooting the problem you found in no time. Value estimate was honest and far less than a dealer repair. This shop is honest!

My initial review:…read more Hello. I've had my previous two oil changes done at your shop. The last time, estimating May-unsure exactly, there was a leak following the oil change. I brought it back and a "new, bigger," plug was placed in order to stop the leak. It continued to drip intermittently. Yesterday, I took my van to the local Honda dealer here in Rapid City. When the techs went to remove the plug, the threads broke off. They were not able to get the plug back in, without leaking. I had to leave my car there, since it won't hold oil. Now I have to get a new oil pan installed, to the tune of $900. This is not okay. How will you remedy this? Thank you. The response: Hello Jory, we are so sorry to hear about the stressful situation with your van and the unexpected expenses you encountered. We want to thoroughly investigate the details of your prior visits, so please send a direct message to CustomerCare@FullSpeedAutomotive.com. We genuinely hope you will give us another opportunity down the road to show you our true standard of care.Hello Jory, we are so sorry to hear about the stressful situation with your van and the unexpected expenses you encountered. We want to thoroughly investigate the details of your prior visits, so please send a direct message to CustomerCare@FullSpeedAutomotive.com. We genuinely hope you will give us another opportunity down the road to show you our true standard of care. Update: I've sent four emails to the email address listed above as instructed, per Stacy. I've received no responses. I've also sent two messages to the shop itself, via the "contact us" tab. Clearly this Grease Monkey doesn't care.

Our truck was making very odd noises coming from the back end. We were half way home, creturning…read morefrom Chicago to the Seattle, WA, area. Did not want to lose additional days getting home. Mark's Auto got us in within minutes after I called. They immediately took it for a test drive, and diagnosed the problem shortly thereafter. Turns out a rear end seal was leaking, causing the truck rear end to slightly lower itself, allowing the heat shield to clang and bang on the drive shaft. They resolved the issue and discovered that the front end 4 wheel drive was not properly activating itself due to a faulty vacuum issue, and they resolved that as well. I was out by 10:00 am and on our way. I want to thank Dan for taking his time to explain the issues so I had full understanding of what was malfunctioning. Can't ask for more than that! We feel fortunate to have worked with Mark's auto and Dan! Now, on our way west! Thanks, Doug LeClair Anacortes, Wa 98221

The level of service here is something other shops could learn from. Thank you for not only getting us taken care of, but also allowing us to fix our trailer in your parking lot while you worked on the truck. Your team made a stressful situation so much easier.

The diesel mechanics said they could repair it for $5000 or remove the DEF system for $1600. I chose to remove it. Now 2026 my truck was stolen and was recovered with no keys. No body in the area would work on it to get new keys cause of the missing DEF system, especially the Ford dealership. I went to Rapid Diesel and talked to them. They said they could take care of my problem of no keys and check the truck out for any other issues. They were great to work with. They notice that the brakes have been rode hard and desperately needed replacing which they did. They were very upfront with everything, no surprises. Next time I need diesel repair in Rapid City there is no question, I'm going to go to Rapid Diesel. I can't say enough good about them, they were great.
