Lakewood Alignment And Brake Service

7 years ago

We have had several of John's cars down for an alignment after he completes repairs. You can tell he knows what he is doing and has a tremendous sense of quality control. There are always good parts used and never any surprises with the vehicles he brings us. Great job guys and keep up the good work! Keep local business alive!

Finding a trustworthy mechanic is worth more than gold! Tempted to keep this find to myself but the shop is already booked out—so clearly you already know about John’s great service! He knows his stuff!

John is an honest guy and knows his stuff. I can only speak for domestic vehicles, but John's usually able to tell me what's wrong over the phone before even seeing the vehicle. I've had my vehicle there multiple times and it's always been returned in good working order at or under the promised cost and on time. I try to do a fair amount of work on my vehicle myself but usually take it to these guys for bigger things and definitely recommend them.

John is the kindest, friendliest guy. He is honest and helpful and has always gotten me taken care of quickly. I've never trusted a mechanic so much. 2023 Update: Still the absolute best. John and his team are indispensable to my family. They keep us on the road in safe and reliable vehicles. We appreciate you guys!

Best shop in town. John took care of my civic all the way to the end of its life. When many shops in Golden were quick to quote me $1,800-2,400 for a repair, John solved my issue with a conversation and a $5 bottle of fluid. One of the many downsides of no longer living in CO is losing my barber and my mechanic.

John is very transparent, and communicative. My husband and I blew a tire coming back from the mountains around 7pm. We got a tow to take us to the nearest mechanic, and luckily that was John's automotive. We were pleasantly surprised how welcoming they were, and how quickly they got to diagnosing our situation considering how we showed up. We have a 99 dodge ram van so parts are hard to find, but John went straight to work calling and got the part in in 3 weeks. After they got the part (steering knuckle and wheel bearing) it was fixed in two days. Even with John and his team dealing with getting sick and being extremely busy. Safe to say we were impressed. Its nice to actually trust a mechanic and not feel like we are being taken advantage of. John gave me frequent calls updating me while we waited for the part to come in. It was really liberating not having to call him myself just to figure out anything. I would highly recommend John and his team! Trust is HUGE and they proved they are worthy of that! Thank you guys again!!

I was looking for a local place to get an estimate on some mechanical needs for my Subaru Forester. John's was the last of the four places I called for quotes and he was by far the best and also just seemed the most knowledgeable. Not only that, but what they discovered to be the problem, was not even what the dealership service department thought and quoted. They not only saved me nearly $2500, but they also actually fixed the issue. I would not hesitate to take my vehicles there. They are super knowledgable, amazing service, committed and stand by their work, and really easy to work with and accommodating.

I had them replace the rear main seal on my car about 2 years ago and it is holding up well. The service was competitively priced, and they were quite friendly. John is quite talkative.

John is honest, straight-shooting, and consistently saves me money And hassle. Thank you! first visit: You saved me AT LEAST $2,000. All the other shops tried to sell me a catalytic converter that I didn’t need. In 2022, my Check Engine light came on. The Honda dealer told me that I needed to get a new catalytic convertor and a knock sensor or I wouldn’t pass my next inspection. So I took my foot off the gas and coasted through every mobile emissions tester for two years straight. My engine light stayed on, and at every oil change, a different shop’s mechanic would recommend a new expense for my engine light. Thankfully, my “coast test” strategy worked for year one, but this week, the registration postcard brought ominous news: Emissions Test Is Required. I shopped around. Honda dealership returned my voicemail and said the Cat would be $1919, and the knock sensor $245. The parts guy, however, didn’t know how much the labor would be. The Reviews for Forever Auto were amazing, so I decided to visit John’s Automotive Diagnostics. “Show me the paper from the CO Emissions Test,” he said matter-of-factly. “Why are you telling me that you need a cat? The engine light on that make and model year doesn’t mean a thing. Go get a test. Here’s what you do: Put some mid-grade or higher fuel in your car. Keep the engine warm while you’re waiting in line at the emissions check. Chances are you’ll be fine.” John was such a friendly, knowledgeable gentleman. Air Care Colorado’s web site says a Check Engine light may be cause for test failure. I went anyway, and revved my engine to about 3000RPM every once in a while without shutting the car off. (I felt like an environmental hazard, yet) I know my Accord runs quietly, smoothly and efficiently. I passed with flying colors, without spending a dime on parts or labor. John diagnosed my needs and helped me unselfishly with five minutes of his valuable time. When I visited for a routine oil change, he also mentioned that the key to my wheel locks was missing. (I had NOT noticed that my old mechanic had not replaced the key when rotating to my snowtires.) in the event that I needed to change a flat I would have been unable to take my own wheel off!…a costly and time consuming emergency. THANKS AGAIN! You are my forever mechanic. You’re certainly not going to get rich off of me, but I talk you up to everyone I know, and understand why it takes a few weeks for you to have schedule availability. 30+ years of honesty, and understanding customers’ unspoken needs, and presenting “if I were you” suggestions without scare tactics attracts other lifelong customers.

John’s place is transparent, communicative, and always does great work! Knew this place was the one when I took my car in with a steering rack issue that was going to take over a grand to fix. John let me know it wasn’t an emergency and allowed me to feel comfortable taking the time to save up some cash for a repair. He even suggested some things I could do to hold my car over until til we replaced the rack. He will always call you with you car's diagnosis and what his plan and suggestions are before doing anything to your car and is happy to do a price breakdown for you. Highly recommend!

John is personable, professional, the process is simple, the work is completed as outlined, and is ready on the day as indicated. There is pride in their work, which you do not often see in other entities such as dealerships, franchises. I appreciate that it is locally owned, independent, and the numerous 5-star reviews. I go above-and-beyond, the extra mile, head-and-shoulders above the required minimum maintenance schedule written in the manuals of our vehicles. I have read every line of them, sometimes sit for an hour on forums reading recommendations otherwise, and then review the material in a spreadsheet of tasks completed, products used, and future, slated, work. From 2017 to 2022 only one mechanic ever worked on our vehicles, including oil changes, wheel alignments, brake pads, among other work. He has a technical mastery of our cars. Due to having twins, wife needed to move, I lost him. Enter panic. But, great news -- I was so pleased with John that I now found a new mechanic. Highly recommend this entity. And, his pricing is highly competitive though I will pay extra for higher quality work.

John is worth his weight in GOLD! Never found a mechanic so trustworthy and fair priced. So glad our friends recommended him years ago Recently bought a new to me car, and if he didn't give it the green light I would've sent it right back. I have confidence going forward because his professional opinion is all that matters. And he's just good people all around, him and his crew! Thanks John

Traveling from NV to MI, we broke down at night & got towed to John's. They were booked out, but helped us get parts & let us do repairs in their parking lot. Joshua checked in once in a while to see how we were progressing. Everyone one was kind, very helpful & supportive. We appreciated their generosity.

Hands down the best mechanic in golden and probably Denver. John and his staff do an exceptional review of your car, address the chief issues, discuss the fixes with you, apply the fixes, keep the costs manageable and get you back on the road safely. You will be very happy and safe if you trust John and his team with your car needs. Thank you John and team!

John and Jason have been taking care of my family's cars for years. They run an honest business, they communicate clearly, and don't overcharge. John has taken good care of my cars and given me great advice on car purchases and work needing to be done. He truly cares about his customers and wants them to be safe on the road. I have come to them in times of need, and they have really come through for me. I always trust their recommendations. It might take a while to get an appointment - they're usually pretty booked because they do such good work! But it's worth the wait!
