Cintech Automotive Repair

09/08/2026

Starting this week, Cintech Automotive is changing our hours.

We’ll now be open Tuesday through Friday from 8:00am to 7:00pm, and closed Saturday through Monday.

The goal is to make it easier to actually get your car in when you need us. Staying open later gives our customers more flexibility for repairs, diagnostics, inspections, and emissions without having to rearrange an entire workday.

It also gives our crew a four-day workweek while keeping the shop open the same number of hours each week, which we think is a better long-term schedule for everyone.

We’ve never been particularly interested in doing something a certain way just because that’s how it has always been done. If there’s a way to make the shop work better for our customers and our employees, we’re going to try it.

So, starting this week: Tuesday through Friday, 8:00am to 7:00pm.

"But the people who sell the car say you can go 10,000 miles on the oil!"

- and they'd be happy to get you into a new car for that same monthly payment.

Oil is cheap. Engines are not.

Check out this absolute garbage sent to our phone. 🚩
Apparently, the "Missouri DOR" is texting people from a Philippines area code (+63) now? Give me a break. These scammers are out here trying to ruin people's day with fake threats about license suspensions and "speeding citations."
This grates us because we’re honest with you about your brakes, your engines, and your oil changes. Being honest also means calling out this kind of bottom-feeding behavior when we see it.

People please:

The DOR isn't sliding into your DMs to ask for money.

That .shop link is about as legitimate as muffler bearings, even though they tried to hide it after ".gov(nkf)"

If you actually had a ticket, you’d either get an introduction to one of Missouri's finest, or get a nice, annoying letter in your physical mailbox, not a text from a bot.

Don't click the link. Don't give them a dime. Just hit delete and get back to enjoying your week.
If you’re actually worried about your car or your record, just come by Cintech Automotive Repair and talk to us. We’ll keep your car running right and make sure you aren't getting played.
Stay safe and stay smart, St. Charles. ✌️

You may not realize it, but the auto repair industry is changing fast. Across the country, yes, even here in St. Charles, small local shops and parts suppliers are being bought up by large investment groups. Usually, the name on the building stays the same, so you’d never know anything changed, but behind the scenes, everything is different. Decisions about what you’re charged, what parts are kept in stock, and how fast a mechanic has to work are being made in a corporate office hundreds of miles away.
When those big companies take over, the focus shifts. It stops being about the relationship with the driver and starts being about hitting "production quotas" and "selling the ticket." That model isn’t necessarily evil, but it’s a far cry from how this industry used to work.
At Cintech Automotive, we’ve decided to stay independent. The people who answer your calls and diagnose your engine are the same people making the decisions every single day. We don’t have corporate pressure to hit volume targets, and we don't have distant management breathing down our necks to prioritize profit over accuracy.
Being an independent shop is becoming a rarity these days, but we’re committed to it. We believe in taking the time to do a careful diagnostic and building long-term relationships with the people who trust us. We’d much rather answer to our customers than to a group of investors.
Thank you for supporting a locally owned business that still puts the work first.

Wow, can you believe it –

This month marks the incredible 30th Anniversary of Cintech Automotive Repair right here in St. Charles! It's also been an amazing ten years since we took over, continuing the family tradition that Casey's parents, Greg and Cindy, started (they're doing great in Colorado and always ask about so many of you!).

Honestly, reaching this milestone wouldn't have been possible without the incredible loyalty and support of all of you, our wonderful customers. You are the heart and soul of Cintech! For three decades, you've trusted us with your vehicles, and that means the world to us. You've kept our doors open and allowed us to build lasting relationships within this fantastic community.

For those of you who might be new to the Cintech family, we've been a family-owned and operated business since 1995, and we're proud to be a NAPA AutoCare Center with a team of experienced, ASE-certified technicians.

You can learn more about our story and what we offer on our website: cintechauto.com. We truly believe in providing honest and reliable service, and we are deeply grateful for the wonderful feedback we've received from our loyal customers over the years.

Speaking of which, if you've been a part of the Cintech story and have had a good experience with us, we would both be so appreciative if you could take a moment to leave us a review.

Your feedback not only means the world to us but also helps others in our community find a trustworthy place for their car care. You can share your thoughts here: https://g.co/kgs/nTRfU6f

Thank you, from the bottom of our hearts, for being the reason we're celebrating 30 years! We're excited for many more years serving the wonderful people of St. Charles.

Shoutout to our Cintech family—you’re the ones gliding through this snow with tires that stick, heat that keeps you cozy, and cars ready for whatever winter throws their way. Meanwhile, to the folks out there sliding on bald tires with no heat… we wish you luck and hope your day isn’t as rough as your ride. Stay safe, stay warm, and just know—it doesn’t have to be this way. ❄️🔥🚗

But FOR REAL - if you don't have to leave your house, just don't do it. After all, we aren't a body shop

We are proud to highlight a member of our team today for his birthday: Ira, our brilliant technician and marine corps veteran. He is one of the best techs in the industry, with a wealth of knowledge, grit and experience. Plainly, he's got that dawg in him. He always solves the most challenging problems efficiently with a great attitude. He is an invaluable part of our family run auto repair shop, Cintech, and a wonderful colleague. He is resilient and optimistic, and we admire his courage. If Ezra could speak he'd probably write a 10,000 word paper on why Ira is his best friend. Ira, we know you're gonna hate this shine but we gotta broadcast it out, you are the best! Happy birthday! 🎂🎉🎁
