- RRRylan RussellMay 10, 20261.0No radiator flushes on Sundays; their mechanic gets special privilege. Might as well be closed, it's bait and switch advertising as far as I'm concerned. I won't be back regardless of what day of the week it is.
- EAEmmanuel AcostaMay 3, 20261.0I called in advance to see how much a high mileage oil change would be and the person over the phone said they just raised their prices to $65. Once I showed up the person that told me to pull into the lane told the driver to tell me they just raised their prices to $100. What was that about?? I drive a 2002 dodge neon. Why would you chose my car to charge extra for?? A little bit shady if you ask me. Won’t be coming back.
- GMGeorge MuradApr 30, 20265.0After dealing with wheat ridge location that has very poor service . They trun me away 4 different times . I made the drive to this location .they gave great customer service. I very grateful to see a location that wanted to help me. I will be going to this location. I will make the drive .
- LCLauren CordovaApr 29, 20265.0The guy was so helpful. My daughter Pulled over across the street because she felt something wrong with the car, turns out a rat was in her hood, chewing up wires and caused the battery to explode. He was generous enough to walk over assist and replace so we didn’t have to move the car.
- JVJulie VasilionApr 27, 20261.0I wanted an oil change and tires rotated. After upselling me and getting the oil change done, he could find a 22 inch ratchet to take the tires off. I didn’t get the service I wanted. This was also the 2nd time I was in bc there was only 1 guy working. I usually don’t have an issue here but today I did. Very disappointed. It cost me $200 for bad service.
