What clients say about John's Complete Auto Service in Wauconda (IL)
-
I recently had service done on my truck for the first time at John’s, an oil change and transmission service. Price was very fair and I was kept updated while they were working on my truck. I would recommend and give 2 thumbs up. On a side note, this is going to sound goofy, but I feel it’s worth mentioning to demonstrate the great customer service John’s has. For a while I’ve been missing a tire valve stem cap on one of my tires. I could have easily bought a pack myself but I kept forgetting. In the meantime I’ve had my oil changed, other service done, holes in tires fixed, etc. at other shops. John’s was the only one to replace the missing valve stem cap, simply because it’s good customer service and it is the right thing to do. A small detail like this is why I will be going back to John’s and recommend them to others. Thank you to the entire team!

These guys always have a fully loaded parking lot and are usually booked up for a week or 2. It's because they are that good and honest. These are honest people making an honest living. I trust them and so many other people do too.

⭐️⭐️⭐️⭐️⭐️ Outstanding service — every single time I’ve been a regular customer of John’s Complete Auto Service for a long time, and I can honestly say they’re one of the best shops I’ve ever worked with. I’m not an occasional walk-in—I’m a high-maintenance customer with multiple vehicles, and they’ve handled everything from mechanical issues, tire blowouts, and electrical problems to getting my A/C back up and running on a 90-degree summer day. No matter what I bring to them, they always make it work. They’re busy (which is a good sign), but they still treat me like my business matters. They’re professional, grateful for the work, and genuinely appreciative of their customers—something you don’t always see anymore. Most people only write reviews when they’re upset, so I wanted to take the time to share a positive experience and give credit where it’s due. This is a quality, trustworthy shop, and I couldn’t be happier with the service I’ve received. Highly recommend.

Best shop ever! Their customer service is outstanding, and they always take great care of my car. Even after moving farther away, I still make the drive because they’re simply the best and I trust them completely. 10/10 recommend!

There’s not much I can say that hasn’t already been said in all of the other five star reviews. There are a lot of them and for good reason—Mark, Juan, Matthew and the others earned it. I have lived in Wauconda for 38 years and John’s Complete Auto Service has proven themselves time and again to be the best full service garage I have found anywhere in the area. In addition to being really good at what they do with cars and trucks, they are great guys who really make me feel respected and appreciated as a customer. If you live in the area, you might have noticed how full their parking lot gets during business hours. There’s a reason for that.

Great experience. Honest owner, there all the time. Wonderful customer service experience. Fraction of the cost of the dealer and quicker. I’d go back and recommend. Mark is a great owner.

5 Stars – Highly Recommend John’s Complete Auto Service in Wauconda is the definition of professional and reliable. I brought in my car with a nail in the tire, and they had me taken care of quickly and efficiently. The service was timely, the staff was friendly, and they were upfront and honest the entire way through. As a military member, I really appreciated how they went out of their way to show genuine respect and support. It’s clear they truly honor those who serve, and that kind of recognition means a lot. If you’re looking for a shop you can trust, John’s is the place. Quality work, fair pricing, and good people who stand behind what they do.

I’m local and do a lot of work myself and have swung by with quick questions or to get a code read before I had my own device and they’re always super quick and helpful. Recently I have a stripped locking lug nut that they were able to get off and will be doing my wheel bearing hub replacement soon. Mark and his staff are great and honest.

Mark and the team at Joh's were great to work with. They are very knowledgeable when diagnosing the trouble I had been having with my car. They also use high quality parts which is rare these days. I was extremely happy with the quality of service that I received and their pricing was fantastic. They are my new go-to shop in Lake County!

I cannot recommend John’s Garage enough. Mark and his entire team are honest, professional and excellent mechanics. I rely on my vehicle for work as I travel throughout the Midwest almost daily. I came in Monday morning with a (serious to me) engine problem and was told, “Ya! We can get to that today”. Their prices are fair and reasonable, plus management is conscious of the fact that their customer base is from Wauconda, and not Wilmette, which says a lot for their character, commitment and concern for the community. I rarely take the time to write reviews, but when I do, it is because it’s worth it to me to recognize and support good people and a great business. Owning and running a small businesses IS A TON OF work, worry and responsibility. John’s Garage will not disappoint, it’s a place you can trust and count on. They are invested in Wauconda, they don’t take it from granted, and it shows!

Very professional, friendly, and quick. I felt comfortable that I'm not getting scammed. Shop is very busy, but still, they have found time for me a walk in. Great respect.

Mark and his team are simply great. Was there yesterday and they right away diagnosed the problem and was able too fix it the next day. Kudos to them. I would definitely highly recommend them. Thanks so much my car runs like a gem.

Mark and team are the best in the area. Honest and hard working, they quickly diagnose the problem and fix the issue right the first time. I trust Mark with all of my vehicles. They always go above and beyond to help any way possible. Thanks.

After searching for a fair price for the rear brakes of an SUV, I finally found John's Complete Auto Service. I called there, spoke to Mark, who was incredibly kind, and told me to bring it in that day. When I arrived, he gave me a ballpark estimate of what it would cost to replace all the brakes (front and back). Mark called me in the afternoon and said only the rear brakes needed to be fixed and would have it ready for me to pickup a few hours. When I arrived he pointed out some other issues that we may want to look at getting fixed. There was no pressure or guilt to do the recommended repairs they found, but rather someone just looking out. I will definitely be back here with any repair needs I have in the future.

This is the best and most honest shop in the area. I've trusted them with all of my vehicles for years and have never been disappointed. I had a 2011 Dodge Durango that the rear heat would not work. Antioch Dodge had my car for over a month, even claimed that they had a technician fly in from Chrysler, could not fix it. John's had it fixed in a day. They have saved me time and money.

Moved to Wauconda three years ago and hadn't needed a mechanic in that time. Needed a radiator replacement recently and brought my car to John's and Mark and company fixed the problem at a very reasonable rate and in a very timely manner. They even will arrange a loaner if you can schedule it. I highly recommend John's Complete Auto if you want quality service, affordable pricing and great communication. They'll get all my business moving forward. And I just bought a second vehicle!

Great honest mechanic! Very affordable, my car is always ready faster than I expect, and they never try to upsell me things I don’t need. A couple years ago they replaced my cracked drive shaft and worked directly with my insurance adjuster so all I had to do was drop my car off, pay the bill, and wait for Progressive to reimburse me for everything minus the deductible. I’ve been a fan of John’s ever since!

Dropped daughter’s car here for brakes and oil change. First class service, great result, and EXCELLENT communication when they struck unexpected issues. They did everything they could to get the car back to us when we needed it. Thanks!

This shop consists of honest, efficient and straight-shooting mechanics who do great work at a reasonable cost. Their parking lot is always overflowing with vehicles so that’s an obvious testament to their popularity. Specifically, I want to share here that the tailpipe from my muffler fell off and I pulled into the nearest mechanic I could find. They told me I needed a brand new muffler installed. I’ve had a lot of good work done at John’s so next I took my car there. The mechanic inspected my muffler and said I don’t need a whole new muffler, that the exhaust system will run just fine without a tailpipe. And he didn’t charge me a dime for putting the car up on the lift and inspecting it. Also, this was not the first time John’s has not charged me for their time and expertise. I will continue to be a loyal customer here and highly recommend John’s.

I came to John's a couple times. They always do good service work for me on my little Mazda 3. No BS not too expensive compared to corporate automotive services like Firestone. They don't always give a loaner out but if you get in early enough you can get one.

Mark did a great job getting to know the details of my car's problems, and then clearly communicating a plan to address them. There were opportunities for him to upsell me on services I didn't need, but he was honest and stuck to the appropriate scope of work. For me, craftsmanship and honesty are the most important qualities of a good mechanic and Mark ticks both boxes. The pricing was reasonable and he even called two days later to follow up and make sure my car was performing as expected. This is definitely a shop worth trying if you're looking for a new mechanic.

Mark and his crew are incredible. I've had repairs and simple oil changes done on my cars, my kids cars and even my mother's car. I can't imagine going anyplace else. They are honest, thorough and timely. They are always willing to help, even you just need a little in your air tire. I highly recommend John's Complete Auto Service for your vehicle needs.

This place's professionalism is still the best and yet they make you feel like you are part of their family. The owner is one of the best I have seen in the auto repair business. I am completely happy with John's Complete Auto Service being my only repair service company for any vehicle. The prices ✔️honesty ✔️quality ✔️are all outstanding. I will definitely HIGHLY recommend them to anyone that I know. Thank you JCAS.

The owner Mark Wolfe is hands down one of the best people I've ever met. Extremely reliable and trustworthy. I'll never take my cars anywhere else. I Highly recommend taking your car here great service at a great price.

Honest mechanics are hard to find. If you're looking for one... these are your guys! Always receive excellent service and they are honest people that really do take care of you. Extremely fair with the pricing and always take the time to explain what's wrong instead of just throwing parts at it and ripping you off like most other places do. Great mechanics and Mark the owner is a really good guy. I've been coming here for 3+ years after being referred here by everyone in my neighborhood. I highly recommend John's for all your car service needs. I won't trust anyone else with my car.

So far so good. I have been to this mechanic a few times for scheduled maintenance and also did a break job. The prices are very fair and the service is friendly. It's best if you can drop your car off and pickup the next day. I have over 20 years driving experience and taking my cars to different mechanics and even dealerships for repairs, so I know how the industry is with looking for opportunities to offer services not needed or nickel and dime for small work. I don't get any of that at this place.
