    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.

    Auto tips from our experts
    1. According to recent studies, 5 percent of all motor vehicle fatalities are clearly caused by automobile maintenance neglect.

    2. The cooling system should be completely flushed and refilled about every 24 months. The level, condition, and concentration of coolant should be checked. (A 50/50 mix of anti-freeze and water is usually recommended.)

    3. Never remove the radiator cap until the engine has thoroughly cooled. The tightness and condition of drive belts, clamps and hoses should be checked by a pro.

    4. Change your oil and oil filter as specified in your manual, or more often (every 3,000 miles) if you make frequent short jaunts, extended trips with lots of luggage or tow a trailer.

    5. Replace other filters (air, fuel, PCV, etc.) as recommended, or more often in dusty conditions. Get engine drivability problems (hard stops, rough idling, stalling, diminished power, etc.) corrected at a good shop.

    6. A dirty windshield causes eye fatigue and can pose a safety hazard. Replace worn blades and get plenty of windshield washer solvent.

    7. Have your tires rotated about every 5,000 miles. Check tire pressures once a month; let the tires cool down first. Don't forget your spare and be sure your jack is in good condition.

    8. Check your owner's manual to find out what fuel octane rating your car's engine needs then buy it.

    9. Keep your tires inflated to the proper levels. Under-inflated tires make it harder for your car to move down the road, which means your engine uses more fuel to maintain speed.

    10. Lighten the load. Heavier vehicles use more fuel, so clean out unnecessary weight in the passenger compartment or trunk before you hit the road.

    11. Use the A/C sparingly. The air conditioner puts extra load on the engine forcing more fuel to be used.

    12. Keep your windows closed. Wide-open windows, especially at highway speeds, increase aerodynamic drag and the result is up to a 10% decrease in fuel economy.

    13. Avoid long idling. If you anticipate being stopped for more than one minute, shut off the car. Contrary to popular belief, restarting the car uses less fuel than letting it idle.

    14. Stay within posted speed limits. The faster you drive, the more fuel you use. For example, driving at 65 miles per hour (mph) rather than 55 mph, increases fuel consumption by 20 percent.

    15. Use cruise control. Using cruise control on highway trips can help you maintain a constant speed and, in most cases, reduce your fuel consumption.

    16. Keep your engine tuned. A fouled spark plug or plugged/restricted fuel injector can reduce fuel efficiency as much as 30 percent.

    17. Inspect the engine's belts regularly. Look for cracks or missing sections or segments. Worn belts will affect the engine performance.

    18. Have the fuel filter changed every 10,000 miles to prevent rust, dirt and other impurities from entering the fuel system.

    19. Change the transmission fluid and filter every 15,000 to 18,000 miles. This will protect the precision-crafted components of the transmission/transaxle.

    20. Inspect the suspension system regularly. This will extend the life of the vehicle's tires.
