John and Greg are both great. This shop is honest and prices are very fair. I’ve had at least 20 vehicles in my 37 years and this shop is the best I’ve been to. I will continue using them and will tell anyone who will listen to use them as well.

Very honest and straight forward. Great local repair shop!

John, Gary and Jeff are always so easy to work with and have done great work every time. It makes getting your car worked on painless and stress free. Thank you from Kyle & Jen!

Great experience! These guys know their stuff! I will use them again.

I had my 1986 Dodge Omni GLH aligned here! It drives perfect for the street and strip. Wont go anywhere else to have my car worked on.

Great bunch of guys very knowledgeable great prices great work would recommend to everyone

Have used these guys for Decades & love it. Honest & through,.....

Great shop, honest guys and quality work!

Great. Guys from stock to super stock place to get your wheels straight

Thank you Maximum Automotive for letting us shoot our student film, Goes Like Hell, at your shop! Thank you John, Gary and Jeff!

I take my 2017 Ram 2500 to John and Gary. In the past I took my truck to the dealership for all my needs while under warranty. However, the alignment was always off, and I felt like I was rushed in and rushed out without any of my questions ever being answered. I had enough and decided to take my truck into John and he aligned it and it has never rode as smooth as it does now! He also helped me pick out high quality tires that fit my budget and needs (not pictured). I love working with the Maximum team because they always keep open communication and they are not hiding anything. If I ever have questions or concerns, they always find the answer and if there is an issue, they find the source of the problem and ensure that it is fixed right the first time. Honest mechanics are rare, and these guys are the best. I would never take my vehicles anywhere else and I would never recommend another shop!

I only trust the best in the business to work on my pride and joy. My car never ran better and drove like a new 71 challenger. They are top notch. I will bring all my cars here for now on very fair and in a timely matter.

Fixed my 1986 thunderbird up enough to get my emissions

Very busy shop, in and out

Great service. In depth evaluation of the issue with the car.

Good friendly people. Did a great job on my Windstar and my sisters Ford taurus

We came back to Denver to buy a used car. They set our appointment and checked the car on time and got us on the road to start our vacation. Weve used them in past from 2006-2009 before we moved back to Texas. Highly recommend Maximum Automation they have always taken care of us.

Trusted John and Gary for over 30 years

My husband has been going to Maximum Auto Service for 25 years. He says they are the most honest and knowledgeable mechanics you find in then Denver area. They diagnose and fix the problem right, the first time.

ABRA sent my vehicle in to these guys for an alignment, and I get it back with the steering wheel 160° off. When I called them to tell them, they blamed it on the upper ball joint, which I find funny because I took it in with the steering wheel straight (see photo for how I got it back). 0 stars - Setting the steering wheel straight is alignment 101. Secondly, nice BS on the ball joint.

John and his crew are the best! Always friendly, accommodating and knowledgeable. They fix everything rifht the first time.

Been working with John and his crew for 4 years. I have no complaints, always top notch service from them!

Really nice honest mechanic with reasonable prices!

I have been using Gary and John for several years. They do good quality work and prices are very reasonable. You cant find too many honest mechanics any more.

The crew does excellent top notch work!

These guys are the best. They can diagnose any problem and fix it right the first time.

These guys are the best mechanics in Colorado, I have been using them for several years and have never been disappointed. They are good honest mechanics

Probably the last honest mechanic in JeffCo

Always helpful honest and professional.

Wouldnt take my car anywhere else
