B&M Auto Repair definitely delivers! After AutoZone scanned the codes for my misfiring truck, I was stuck waiting 2 weeks for a dealership appointment. But B&M got me in and out within 24 hours, handling my warranty claims directly. Their professional service and expertise got my truck running smoothly again and it's been running amazing ever since

Had electrical / computer issues. Fixed issue to where the truck would operate just without dome lights. I had the truck towed round trip by AAA. The mechanic was reasonable. Still works to this day 3 years later. 😁 This it my third repair from B &M Automotive and greatful for having my truck back in service. Professional , respectful and pleasant to do business with. Cost was less that estimate. Happy days.

Bob and Gary take the time to explain the issue that can be understood by the customer. They do excellent work at a very reasonable rate. I drive across town to use their service which costs me a bit extra in Uber fees but they are well worth it. Finding a good trustworthy mechanic is as difficult as finding a good Dr or lawyer which is why I'm sticking with these guys.

I flip cars here and there and I take all mine to these guys at B & M. They are very thorough yet cost efficient. I'm very pleased with our relationship!



07/24/2023

I really appreciate these guys! After moving from out of state and having a solid mechanic you have trusted for over 14 years, it's like having to find a new doctor too! I am so thankful I found these guys! They have been so helpful and honest every single time! When I first moved here, I worked for UPS using my vehicle out of Oliver Springs. Let's just say that was not good. I've had issues ever since. Going up and down mountains was hard on my vehicle, and unfortunately, my light came on. I knew it was the transmission. I took it in, and they went thru it and told me they would check out everything they could and get back to me. Sadly, it was my transmission. They were super kind, and we decided it would be better to just get another vehicle, and they agreed. I really appreciate their honesty and hard work! Like I told them when I left...I will be back with the new vehicle because I know I found my mechanics for life here in Tennessee!

Thank you B&M Automotive! They are Honest, Experienced, and affordable! The first place that I took it to said that I needed another motor and boy were they wrong. I'm glad that I found B&M and they were quick to let me know that I did not need another motor. They knew exactly what it was and had it fixed in no time. I highly recommend them!

I had an amazing experience here at B & M! Both my mom and I had been having problems with our Toyota Priuses, this is the closest shop that works with hybrids but unfortunately we live about an hour and 15 minutes away. Boy am I glad that we drove this whole way! We arrived there as they opened and told them about the cars problems and stayed to chat for a while. Marty, the main mechanic mentioned how they had been operating with just two employees and the manager because everyone else had quit. Because of that they were unsure how soon they could get to my car. I wasn't super happy about that but I understood that it was out of their control. Because I was trying to leave shortly for the start of school, I really didn't have much time to waste, but again, they couldn't do much about it. My mom and I had about a days worth of errands to run around Knoxville so we told Marty that we would be around for that day in case they miraculously finished with the car. About an hour or two before they closed we got a call about the car. Unfortunately, my car was totaled, but because they were so fast with their diagnosis I still have plenty of time to figure out what to do as far as school goes. I would highly recommend coming here for your auto repairs. They were very considerate to my need for quickness even through their rough times, they were all very personable and I really enjoyed standing there listening to them talk, and so if ever I come back after college, they have gained themselves a customer for life. Thank you so very much Marty, Bob, and Gary.

I had them do some repairs on a somewhat Frankenstein VW trike I just acquired. They did a FANTASTIC job figuring out what I had and then getting it road ready. A special thanks to Diego. Dude, you are my go-to guy for anything I need on this trike. Awesome people and awesome service.

Highly recommend B&M. They made every effort to fix my Immobilize and ECU. When no one else could or wouldn't take the time to try to fix it. Had issues with the fuel pump and they kept at it until all issues were resolved. Very polite and professional. This place is awesome.

I had hit a curb on a Saturday evening, and blew two tires. I came to a stop right in front of B&M. I managed to get my pickup truck into their parking, and left it for the weekend. Monday morning I checked in with Marty, and he worked me in, and got me two tires. He also checked underneath, and found no damage. Good service, fair pricing - I will use them again.

Our diesel truck broke down in Knoxville 100 miles from our home. B&M were helpful, kept us informed, and performed the repair at literally half the cost quoted us from a dealership in town.

Three of our vehicles have gone in here, and we've been pleased each time. Two had appointments and were out same day, one didn't and took for days to fix a somewhat exotic issue. Replaced brakes, rotors, and calipers on a small sedan. Work was done quickly and was very nicely priced. They still work great six months later, so I'm pleased with the job their mechanics did. Fixed the heat/air on a pickup. Took the day to do because a part had to be ordered, but reasonable time frame, considering. Very reasonable price, as well. Still working great, so husband is happy with the job. Fixed the air on a small suv that had been in multiple times for the same issue at another place. This one took four days, but we also hadn't made an appointment and it turned out not to be what we had been told was the problem. From the first place, we kept getting the car back as fixed only to have the ac quit working in the same day. Four trips there, and we were told it would be $1800 to replace the compressor. Took it to B&M, and they looked beyond the obvious. Turns out it was an electronic thermostat switch that had died, and $400 later, the system runs as well as it did 14 years ago when it was new. True these guys. They're honest and dependable, and I highly recommend their work. 10 stars, fellas!

I had called Bob and also spoke to Marty who made my experience and service here so professionally great. I was told by a local Express Oil Change Lube that my Oil Plug was too tight and may be a Leak and problem with my Differential Oil Plug, etc. may have a leak or something wrong. Well after Marty had checked and showed me there was No serious or any problems at all I was so thankful. I ask them to do my synthetic oil change and wasn't charged extra for checking out my vehicle. I would Highly Recommend this Professional Auto shop and these great mechanics to work on my vehicle or anyone else's. They deserve to be recognized as Top Professional Mechanics in Knoxville! Thank you Bob and Marty for great service. I will be back !!

AMAZING team led by Marty's strong shop leadership and the award-winning, 30+ year owner Bob! Dan at the service desk gives you his full attention and seems to multitask without missing a beat. They don't talk "over your head," but in terms that make sense! Their intuitive analysis of several problems with both my truck & husband's car were confirmed after they inspected vehicles. They finish on time & follow up during work. Polite, knowledgeable, great sense of humor, honest & super friendly! JUST WHAT YOU WANT & NEED IN A REPAIR SHOP!
