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 was stranded at the grocery store after my appointment for an oil change with Car X. The oil had…read moreleaked out from an untightened oil filter that was neglected on my car. I trailed oil all through the parking lot at the store and someone noticed it. The oil was at less than 1/2 inch on the dipstick. We put 3 quarts of oil in it and I drove less than a quarter mile to a Valvoline store. Photos indicate severe leakage. Valvoline has a two-step process where the person under your car doing the work is prompted by a person next to your car yelling out checkpoints as these checkpoints are checked you have the confidence that every necessary step is completed. When I went to CarX for a refund, the manager, Dave was argumentative with me and mocked me. When I described the situation I had. He told me I didn't need to get snippy. I voice recorded the entire conversation with him. I've never done that before, but I think I was onto something because I do have proof. I have videos and photo images from the technician at Valvoline that helped me. I will never go anywhere except Valvoline again.!!! and Car X was nearly responsible for total engine failure on my 87,000 mile car!!!!

First off you make an appointment with the call center. Which ok whatever, but the manager had to…read morecall and cancel it and move the appointment. No biggie except I missed the call and picked up mid voicemail. So I called him back. I said just confirming the voicemail the manager legit said well didn't you listen to it. I said it broke up so I'm just confirming. He said yea that's what I said. Ok cool. My kid took the car in I had gotten a free oil change thing. Manager calls me. You never told me about this free oil change. I said I told the call center. He was so aggressive about it. My son said he was also rude to him in the store.

I talked to Josh, who told me what he thought the issue was, even though I didn't tell him any more than the symptoms. I believe in shopping locally, and he passed my first test. I dropped the car off overnight and got a call first thing in the morning with a complete diagnosis. Josh worked with me on what I could afford and even let me know about finance options (No interest for 6 months - NICE!) I got the work done that I could afford, it was done quickly (before noon!) and it was done courteously. A huge "thank you" to the owner and employees for rewarding me for shopping locally. You've earned my business today and in the future. A trustworthy mechanic is a HUGE value for a used car driver like myself. Thanks!
