We had taken our smoking engine Subaru to this shop, and they had dyed our fluids for us and did some investigation. After receiving our car back and driving it around for another week, we brought it back, and not too long later, they gave us pictures, videos, and call with everything that was wrong with the vehicle and offered a very fair price for fixing our vehicle. Everything went great for a couple of days, and our engine started to smoke again, we gave them a call, and they had taken our car in again. After discerning that this wasn't caused by us again, they honored their guarantee and repaired the engine again, going the extra mile for us. I'm extremely appreciative of all the hard-working fellows here that go above and beyond for their customers. Not to mention their patients with us explaining everything that is going on to our car-stupid selves! If you need a car mechanic, I highly suggest Colorado Tire & Service. I now have my 2nd car in this shop and once again am very pleased with the service that is being provided!
