Muffler Doctor & Auto Clinic in Cottage Grove was great. Needed muffler repair on one of our cars…read more Didn't want to spend much as this car bluebook value is really low (although any good running car is invaluable these days) Was pleasantly surprised by Muffler Doctor. I called, and they suggested I really had to come in, which makes sense. They gave me options/pricing, and really tried to keep the price low. The dealership quoted me $4,000 (to be clear, dealer did say 'shop around') to repair whole system. I drove out of Muffler Doctor with a repaired, safe, car for just under $200.

Ive brought every car I've owned to Muffler Doctor. Tires and brakes mainly, but it's always a…read moregreat friendly experience. No appointment needed, PLUS my car is always done the same day. Today I brought my Subaru in for brake pads and rotators... I thought easy fix. Well I was informed I needs calipers too. $900+ visit... after speaking with Tim, I remembered I had an extended warranty. After all was said and done, the Subaru dealership has to replace everything due to a manufacture issue. Tim was helpful through the whole process, and charged me NOTHING. When I asked if I could at least pay something for the diagnostics, he stated "oh no, I mean I would hope someone would do this for me in your situation." You do not find that kind of customer service anywhere now days. Most shops are all for themselves and how they can make money. It's great to know there are still good businesses and business people out there. Even the advisor at Subaru mentioned the guys at Muffler Doctor are good people. So if you're looking for a great place to bring your car... this is the place!

I love this place for tires. I have gotten 3 full sets of tires so far at this place. You need to…read morecall, but they always have bent over backwards to make it happen asap. The last 2 times I called, they were able to get me immediately. Once for tires and once for a nail puncture repair. It bothers me to see a one star review. I know people usually do not leave reviews unless they are angry, so I am here to say I have never had nothing but EXCELLENT service at this Cottage Grove location. The managers name is Tony. I don't personally know him, but have remembered his name after the 3rd visit. He also seems to treat his workers well. Highly recommend for tires or tire service. I have never had any mechanical repairs there.

Took my car in for $300 worth of stuff including a fairly priced oil change. They didn't fully put…read morethe cap back on. My car was covered in oil. It is still costing me money. Took it back to them to degrease, they sprayed it down maybe 10-15 minutes the first time, after I had to have it towed to a mechanic and have the serpentine belt replaced. My serpentine belt was soaked in oil and ended up warping and fraying. The manager said he's been working on cars since the 80's and that doesn't cause the serpentine belt to wear down, even though my normal mechanic said otherwise and there are lots of articles on it. I had to take it back in for them to degrease it properly on a lift for the second time after my belt snapped and frayed, manager fought me the whole time. Long story short, don't take your car here unless you can pay for the damages they will cause in the future.
