What clients say about ASF Repair in Knoxville (IA)
they where great heading to the races win are truck broke front drive shaft they pulled it out for us and got us back on the road best 100 bucks ever spent thank u guys for your help highly recomended
Great shop that does high quality and honest work at affordable prices. They don’t try to sell you things you don’t need, but make sure you are taken care of. Looking forward to working with them for years to come.
Prompt service. We are so pleased we found them. Thoroughly explained our vehicle's issues. solutions & potential costs. Pleasantly surprised us when ASF presented the invoice several hundred dollars under quote! They only did what they needed to do to get our truck working efficiently. Highly recommend this trustworthy business & we will use again in the future
Took my truck in this past Monday (12/15/2025) to have it serviced and to have it diagnosed for the cause of death wobble, techs were quick to diagnose the issue and also found out the front driveshaft was about to come loose, overall my experience are ASF was very good and will be returning there.
We were driving through Iowa and had car trouble, most shops wouldn’t even entertain us but they got squeezed us in between appointments and had us back on the road in a few hours. Great people to work with and very reasonable pricing
We recently switched to ASF and have found through experience that they are honest, thorough, prompt, and explain things very well. It has been a long time since we have been confident in a mechanic, but these guys are worth the drive, and their honesty and work ethic are very much appreciated.
Scheduled for 11:00 a.m. arrived few minutes early, took us in on time, facility is located out in the country, no concerns about that, very well maintained shop. Noticed employees keeping air lines rolled up (safety and preventing damage to air lines). Person performing work came in to speak to us after completing the work.
Lady scheduling work and running the shop very knowledgeable and customer focused. She ordered cabin air filter day before Scheduled service. When asked why she stated "most overlooked filter on vehicles".
Overall great experience at ASF Repair!
Sincerely,
David and Wendy Drake Pinetops NC
Jon and his team at ASF Repair do a great job with all of my vehicles. Their prices are reasonable and they do great, quick work.
I have been happy to have them handle everything from a transmission replacement, to tire purchase and installation, to suspension work, general oil changes and maintenance.
I am always quick to recommend ASF Repair when anyone is wondering where to take their vehicle.
Top Notch mechanic!! He and his team have worked on several of my vehicles and they fix it right the first time, every time. From diagnostic troubleshooting, to having an engine rebuilt, to simple part replacements, ASF has never done me wrong.
Jon and his team are always quick/efficient when I need an oil change or vehicle work done. Always willing to work around my schedule as well. Would recommend highly!
They are the best people and mechanics in Knoxville and surrounding areas for the way they service and treat their customers. I'm always satisfied with their honesty. Thanks Jon Lang and your team.
Super helpful people. They get stuff done quickly, correctly, and efficiently. They’re honest and good people. This is the only place I plan on taking any of my vehicles. I highly recommend you getting everything here as well!
10/10 recommend. They do great quality work. They were able to tackle my not so easy repair, and had it completed in only a couple days. Very satisfied
Jon and the crew are very knowledgeable and friendly, a fast growing rural automotive repair shop that also has a firewood stand. :) Bring your truck in for an oil change and take home a pile of fire wood for a camping trip. :) They also offer pick up and delivery of your vehicle incase driving into the country isn't your cup of tea.
