    My car

    This is the only place I go to get my oil changed. I trust these people and always leave with a piece of mind, which is very important to me; there's not a lot of people you can trust with your car. If there's an issue with my car I know they can guide me on what to do with their expertise. They are always professional and nice people. Josh and his team always go out of their way to help. Highly recommend, you won't regret!

    I was sexually assaulted by one of the technicians at 8080 E. Mississippi Ave Denver,CO while getting my oil changed. It happened a couple of months ago, however, I am still traumatized. Stay far away from Grease Monkey #14!!!!

    Like most mom n pop shop, this place is a gem! Super nice and polite family that will work on your car carefully and thoroughly. Another thing I really appreciate about this auto shop is that I will never have to worry about being ripped off from these people. Pricing for conventional oil change is a little bit more than other chain auto joints but I would totally pay more for a peace of mind and effortless experience. Highly recommend! P/s: the main office will be on your right as soon as you turn after the yellow "50c car wash" sign from Parker.

    First I want to say I tried out this grease monkey because they had no wait and they were near the vet I take my dog to. I dropped off my pupper and came in here for a much needed oil change. It took a solid 5 minutes to flag down a staff member because they don't come into the waiting area often. The access is wonky, you can only drive in from EB mississippi, so the approach was awkward. They charged me close to $70 for an oil change. It's a steep price! I've never paid more than $40 at other leading businesses. Grease Monkey neglected to rotate my tires, they neglected tell me my front brakes were almost entirely gone, and didn't bother to notice that I had a leak from under my car. Oh, but I was in and out in under 20 minutes. I would much rather wait the extra 10 minutes and find out if my car needs anymore work. I feel like I got a $25 service for almost triple what I paid. I recommend going elsewhere for quality service. If you want a quick service this is a good place to go, otherwise I recommend taking your hard earned money elsewhere.

    These guys have helped me so much with all my car problems. They are consistent and efficient and I…read morewon't go anywhere else even for advice. If you want a mechanic who will be real with you and only fix what needs to be fixed, these are your guys.

    This was going to be a five star review until I looked up the parts pricing on Google versus what I…read morewas charged on their invoice and that I specified I wanted aftermarket parts, not OEM. Basically feel like I was taken for at least $180 and up to $400 bucks. Quite the bummer as everything else about my experience was so good, I didn't even mind the $130/hr service rate. A shame. Something in my 2009 Nissan Versa blew up and ALL the warning and error lights lit up on the dash. Car would crank but not start. I thought it was probably the fuel pump but beyond my current ability to diagnose and repair. Had it towed to ATR. They were prompt in diagnosing and David called me to discuss the necessary part. I asked for aftermarket but by the price listed on the invoice they charged me OEM MSRP $486, which leaves me very disappointed. I found the same part for $355 on the NISSAN WEBSITE, $330 via simple Google search at local autoparts stores, and other aftermarket on Amazon and ebay for $50-$60. So, I could have literally walked or taken the bus two miles away to the auto parts store and saved $150, or ordered online and saved $400 bucks. Again, quite disappointed with this markup, especially given $130/hr service rate. They also found my one of my axles was leaking. He quoted me a full replacement of the axle but it turned out they could just replace the boot so it was quite a bit less than the quote when I got there to pay and pickup my vehicle. Sadly, overcharged for this part as well - paid $79, found on Nissan's website for $46, ebay for $36. Turnaround time was quick. Labor is $130 an hr as I mentioned, they have all the tools and knowledge to diagnose and repair so I don't have a problem with that rate, but the parts pricing thing is disappointing. (Oil change was $35 including oil and filter. Tire rotation for $16, reasonable.) The office is very clean and minimal.

    By far, this was the worst experience I've ever had with a company working on my vehicle…read more I initially brought my car in because the check engine light came on. After running diagnostics, I was told the issue was related to a knock sensor misfire. Instead of recommending replacement of the knock sensor, I was advised to get a $600 tune-up in hopes that it would resolve the problem. I trusted their professional recommendation and agreed to the service. Unfortunately, immediately after the repairs were completed, my vehicle was still experiencing the exact same issue. I contacted the shop right away, but because it was late Saturday afternoon, I was told I would need to wait until Monday to bring it back in. When I returned Monday, I spoke directly with the manager and explained everything that had happened. He told me that if the issue turned out to be the knock sensor after all, he would cover the cost with no problem. We scheduled for me to return Thursday morning. On Thursday, after the technicians confirmed the knock sensor was indeed the issue, I explained that the manager had already agreed to cover the repair. However, I was then told that because the manager was unavailable, there was nothing they could do and I would need to come back again. When I returned Friday, the manager completely changed his position. He stated he could not cover the repair because, after speaking with the technician who originally recommended the tune-up, they decided it was simply a "process of elimination" to diagnose the problem. After wasting $600 on unnecessary repairs, I ended up taking my vehicle to Big O Tires. They replaced the knock sensor and informed me that I simply needed a Hyundai system update afterward. They also told me the tune-up I was sold was unrelated to fixing the actual problem. I feel completely misled and taken advantage of. I trusted their expertise, spent hundreds of dollars on repairs that did not resolve the issue, and then was given conflicting information and broken promises from management. I would strongly caution others before bringing their vehicle here, especially if you cannot afford to waste money on unnecessary repairs.

    I went in and they were able to keep my appointment time they showed me everything that needed to…read moreget done and didn't make me feel like I was dumb for not understanding they were kind and worked with me abs made a plan that I was able to afford and were very transparent with me. They were prompt and keep me well informed and preformed the services I requested without tons of upsell and were just great I don't know about other breaks plus locations but this one was AMAZING cannot recommend enough
