Normally I do our oil changes but today my wife decided to try Grease Monkey because our AAA…read moremembership shows that Grease Monkey offered discounts to members. Was that a mistake. She came home disgusted with the way she was treated. The guy behind the counter was rude and condescending to her. When she asked about the AAA discount the dudes reply was "Nope, we don't give discounts here". He then proceeded to try and up sell other services such as filter and other fluid changes. When my wife said her husband can do all of that the jerk started quizzing her about if her husband was a mechanic. When she said no he is just into repairing cars the guy mumbled something under his breath. My wife asked him what he said and his reply was "I doubt he can change the transmission fluid in his garage", which is not what he uttered the first time. Evidently these guys do not read these reviews because a two star rating tells you all you need to know. Avoid this shop like the plague unless you want to spend more than you should and want to be treated rudely and unprofessionally. We are one and done with the Northglenn Grease Monkey.

NEVER. GO. HERE These guys are thieves and goons…read more Literally go anywhere else. I have never felt compelled to write a review for a business until the HORRIBLE experience I have had at Mud's Tires. They've got GOONS working there and this shop should be avoided at all costs. Earlier this year, I brought my Jeep into Mud's to see what it would take to get my check engine light turned off. Well, 14k later, my check engine light is still on. This is the most back-alley and illegitimate mechanic shop I have ever dealt with and I am embarrassed I ever went here. After having to bring my Jeep back into this shop and having it stay over night there for a total of 60 days this year, I decided to cut my losses and accept that these dirtbags were never actually going to honor their "warranty." Mud's claims to have a warranty for all work performed but they won't actually honor that, when you inevitably have to bring your car back in when their shotty mechanic work immediately fails. They will try and convince you that you have to spend more money with them to actually fix the problem this time. They will pretend to work on your car while they keep it for a few days/weeks and you are without a way of getting around. This happened to me and when I complained to the owner he tried to gaslight me and tell me the issues I was having with my Jeep, after paying him thousands, were somehow my fault? I've attached a screenshot of the convo to this review, in which the owner of the shop tells me "I'm not your daddy," after I complained to him about the mechanical work the goons he's got working in there did on my Jeep. Also, I recommend scrolling down a few reviews to read about one customers experience at Mud's in which she over hears the owner complaining about "blacks." This is the kind of shop Mud's is. NEVER GO HERE. They will rob you and your car will run worse than it did before you brought it in. The owner will act like he's your friend and that he's giving you a deal. Run. He's a hustler and don't fall for his tricks. He is not your friend and he will rob you blind if you give him the chance. Lastly, I asked the owner for a 6k refund after his goons essentially totaled my Jeep and he said he would sue me for defamation if I gave him a bad review. I've attached a screenshot of that interaction with him as well. Apparently customers take him to court often? Go to a real shop that can actually honor their warranty and has actual licensed mechanics.

Something about the interaction did not sit right with me, so I pulled over shortly after leaving. I discovered a bolt that was nearly falling off -- an issue that simply required tightening. Despite this, I was quoted approximately $700 for upper control arm bushing replacement, which appeared to be completely unnecessary based on what I found. That experience seriously raised concerns about the accuracy of their inspection process and the recommendations being made. Bradley and the individual managing the service desk did not inspire confidence, and unfortunately, I left feeling that the diagnosis and suggested repairs were not trustworthy. I would strongly encourage others to seek a second opinion before approving expensive repair work here.
