    AVOID THIS AUTO SHOP AT ALL COSTS!!!…read more The mechanics at this shop are simply uneducated and unprofessional at what they do. I had trouble filling my car with gas. Every time I go to a gas station and start pumping gas into my car, the pump randomly stops but my gas isn't even close to full. So I had to continuously press and press the gas pump until my car was full of gas. So I took it to Reds to see what was wrong with it. The guy there said the Evaporation Canister and Vent Valve needed to be replaced. So I gave them permission to replace them. When they got it fixed I took it back to my local gas station and my car still had problems filling up with gas! I called Reds to set up an appointment to get it looked at again. So I had to drive all the way to their auto shop in Lockwood and drop off my car again. (I live in Billings by the way) The next day they called and said that they needed to install a vent hose in my car. I gave them permission to do so. After they installed it, they took my car to a nearby gas station at their auto shop and filled it with gas to see if it had any problems. Luckily it didn't. When I got to their auto shop to pay, they told me that they had to spend $10 to fill my car with gas to see if it was fixed. They said that I didn't have to pay for that. However, after I paid for the work to be done, I saw on the receipt that I was charged $10 for the gas that they put in. I then asked one of the mechanics if replacing the Evaporation Canister and Vent Valve was necessary to resolve the issue of filling my car with gas. He said that he wasn't sure and there was a chance that I didn't need to pay the amount of money that I did to get it fixed (which was $800). There was another problem that I had with this auto shop. I noticed that my car was leaking oil. I took it to Reds because they already knew about it when I bought my vehicle. They told me to bring it back to them if I noticed the leaking had gotten worse, which it did. I called and told them that I needed this leak fixed. They fixed it, but they replaced my breaks too, which I gave them NO permission to do so. I noticed this after I paid and received my receipt. They charged me an extra $368 for something I did not ask for. When I called Justin at the auto shop for an explanation and a refund, he said that I gave them permission to do my breaks, but I never did. I also called Eric, the owner of the shop, to explain what had happened. He never believed me and both he and Justin were unprofessional and rude in their responses. I would've never thought I would run into as much of an unprofessional owner and worker as Eric and Justin were. After all of this, I never got my money back. The employees at this auto shop are greedy and only care about your money. They don't care about you as a customer. This is the worst business I have ever been to and I will NEVER trust them with my vehicle ever again. Take your vehicle to another auto shop other than this one that will actually value you as a customer, won't rob you of your money, and will know how to operate a vehicle correctly.

    Reds has worked on my granddaughters Jeep a couple of times in the last few years. Of course it is…read morealways a crisis when she gets a hold of me because the Jeep is not running. Well every time I have her take it to Reds they get it done and for a fair and reasonable price. The work that they do is awesome and they always let you know what they are doing and get your input The only place I would have work on her vehicle
