What People Say About Us

  • reviewicon

    Left my car there while on vacation, kept me informed, car runs great. Fixed a seal, stopped oil leaking, and established I needed a new battery. Thank you, Tracy and Linda Norris!

  • reviewicon

    Got us in last minute for some repairs that could have been catastrophic if we continued down the road. They could have easily gouged us knowing we were in a pinch and just trying to get home but were upfront, honest and personable. Would recommend to anyone.

  • reviewicon

    Incredibly impressed with the service and how informative our experience was. They were able to get us in on very short notice and explained to us exactly what was going on with my car. I definitely plan on coming back for any mechanical needs that we may have in the future.

    This shop is absolutely fantastic. These guys went out of their way to fix our problem. We are from Spokane Washington and we needed to get home. These guys worked outside in 30 degree weather to fix our RV so we can make it home. If I'm ever in the area again and need work done these are the first guys that I will go to, to have it completed. The owner even went out of his way to call me to make sure that I made it home okay. Thank you so much for going out of your way to make sure that I made it home and our RV was repaired.

    Great staff!! Great service!! Had a emergency while traveling and showed up one morning with some work needing to be done and was able to fit me in and get it done. Had my own parts and price was very reasonable. Would definitely recommend this shop.

  • reviewicon

    I highly recommend this business, they got me in on very short notice and fixed my car right away. Their prices are fair, and the customer service was phenomenal. I will be coming to them for all of my car maintenance in the future!

    Cole is great to work with! I had a problem with my wife's care and he was able to find the issue and replace the part. I was able to use the car while we waited for parts. Every aspect of their work was great.

    Friendly, straightforward, and honest. We were just traveling through and I feared some kind of up sell. Nothing like that happened. I wish I lived in Gillette so I could take my car there all the time.

  • reviewicon

    Honest people doing a good job is hard to come by, but they hit the nail on the head. My husband and I will definitely use them again. Friendly staff and a great job done what more could you ask for! Thanks guys.

  • According to recent studies, 5 percent of all motor vehicle fatalities are clearly caused by automobile maintenance neglect.
  • 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.)
  • 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.
  • 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.
  • 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.
  • A dirty windshield causes eye fatigue and can pose a safety hazard. Replace worn blades and get plenty of windshield washer solvent.
  • 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.
  • Check your owner's manual to find out what fuel octane rating your car's engine needs then buy it.
  • 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.
  • Lighten the load. Heavier vehicles use more fuel, so clean out unnecessary weight in the passenger compartment or trunk before you hit the road.
  • Use the A/C sparingly. The air conditioner puts extra load on the engine forcing more fuel to be used.
  • 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.
  • 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.
  • 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.
  • Use cruise control. Using cruise control on highway trips can help you maintain a constant speed and, in most cases, reduce your fuel consumption.
  • Keep your engine tuned. A fouled spark plug or plugged/restricted fuel injector can reduce fuel efficiency as much as 30 percent.
  • Inspect the engine's belts regularly. Look for cracks or missing sections or segments. Worn belts will affect the engine performance.
  • Have the fuel filter changed every 10,000 miles to prevent rust, dirt and other impurities from entering the fuel system.
  • Change the transmission fluid and filter every 15,000 to 18,000 miles. This will protect the precision-crafted components of the transmission/transaxle.
  • Inspect the suspension system regularly. This will extend the life of the vehicle's tires.
