They gave me great customer service. They kept me informed the entire time my car was being serviced. They worked with my warranty company and helped me understand the process
The only thing that was agony was not having my car for more than 3 whole days. But they kept it to make sure everything was right and it didn’t shut down on me. Been over a week that I got my car back and it is running great. They make sure everything is right so I don’t break down again. Would highly recommend them.
I highly recommend this location! They are so friendly and accommodated me that day. The service was fast and well done. I will be taking my car there from now on.
I love this Car x compared to the one in Ofallon on hwy K. I called Jeremy at the St Peters location and he was able to give me an appt for the very next day. Also he got me in and out in less than 35 minutes. I will definitely be going back. Thanks again Jeremy ♥️
My mom and I have been going here for over 10 years. Best service, reliable, helpful. They do not over sell you. Eric, the manager, cares about his customers and will make sure to everything he can for you. Great store and family owned!!!! I cannot recommend this CarX more.
The owner is very easy going and easy to work with. Gives a honest price and keeps it simple. promised to get the work done in 1 day and delivered. This was my first time using this business but it will not be my last. I recommend this shop to anyone looking for a pleasant experience.
My check engine light came on late one afternoon, soon before they closed. I called and talked to John, and he told me to come in at 7:30AM in the morning. John discovered that my oil was low, and he discovered that the oil had metal shavings in it. He suggested an engine flush along with an oil change. John also informed me that the diagnostic code had certain engine parts assigned to it. John feared that parts of my engine may have been compromised, which would be an expensive repair. John suggested that we wait to see if the engine light comes back on after the flush and oil change. So far, the engine light has not come back on. He said if it does to bring my car back.John was very caring about my concerns. He seemed well educated about my issue, which made me trust him. Bernie was also very friendly and empathetic. He took very good care of me when I arrived and when he closed me out with paperwork to sign. I had a very good experience and I won't hesitate to visit them again if I have future car needs.
Not enough good things to say about Bernie. He went above and beyond. Not only is he super personable and incredibly friendly but he couldn’t be more accommodating. We live 1.5 hours from this area and our car was making a sound. We called on a busy Saturday afternoon and he said bring it right over and he’d be more than happy to have his guy look at it. They did so and did so promptly so we could get on our way safely. If you live nearby or even out of town and caught in a situation like us… absolutely use this business for any needs you may have. They couldn’t have a better person in charge. Thanks Bernie for your kindness. Keep working hard and loving life!
This is the best car places I've ever been to. It honestly feels like taking your car to a trusted friend or family member that knows cars really well. Never once have I felt taken advantage of or over sold. I would always come to this location for car help and repair. And pricing always feels fair as well.
They are proficient in prioritizing the customer’s experience. I would definitely recommend using them for any of your service needs, as I will definitely only be using them from here on out.I was able to be seen right away; the staff is incredibly nice and helpful. They explained all that was being done to my car. I had coolant leaking from my car. I called, and they saw me the next day. After a speedy diagnosis my radiator was replaced. They even took it a step further to run additional diagnostics to make sure the leak caused no other damage to the engine. At my request they performed even further diagnostics without hesitation.I returned at a later date when my car failed to start, due to corroded terminals. They made another speedy repair, and got me back on the road.
I called several places to try to get my car in before a holiday weekend with no luck. Car X was able to get my car in the same day and repaired within hours! Prices were reasonable and my car is running great again. Very appreciative of Zach and the staff at Car X St Peters!
Zach is the best if you need someone to help with your vehicle talk to him
Called first thing in the morning for an appointment so that I could wait for my car. Steph was very polite and accommodating. She gained her trust with me as far as being up front and honest about what needed to be done to my vehicle. It made me feel very comfortable and it felt good knowing that I was not getting taken advantage of. There needs to be more people with her work ethics in this industry. I will definitely continue to do business here with someone like her working the front line.
Outstanding service at CarX. Thank you for being so thorough. Went for an oil change and through further inspection I needed new brakes. The technician explained everything well and price was reasonable. Thank you for making me feel safer!
I came in today to get an oil change, and the manager Stephanie was very nice, and professional, knew her stuff and made me feel very good about the sale! The oil change was quick and I was on my way in no time! Definitely will be back there for any service I may need in the future!
Great service and lovely people right here. This is a place that feels like home. 10/10 recommend Andy he's awesome!
When I say they go above and beyond for their customers!!! I'm still at a loss for words at how much Steph did for me! She earned my business for life for this company! She treats her employees with respect and goes to bat for them too. It's nice to see and experience in a world where it's everyone out for themselves! She deserves a raise and promotion and all the respect and praises! Her Mechanics, follow her lead and give their all as well! I'd give more stars if I could and I usually don't review many places! Phenomenal job!!!
Great service. Had a punctured tire and they were able to fix it quickly on short notice. Andy was great and very helpful. Good experience.
Service was awesome and Andy, the manager, was great to deal with. Happily will come back!
Great job. Got me in right away. Thanks!
Absolutely love the new manager Dan! He has not only turned this place around, but he has actually made the process easy and trustworthy!!! Seriously, I had my hopes up for coming back here after my last experience but someone said that the new manager had really fixed up the place!We love it here now! Thanks Dan!
I visited this location for my state and emissions tests. I had an appointment and they completed the tests in a timely manner. I had a coupon for a free state inspection and the waiting room was very clean. All around a great experience.
Very professional customer service. Very fast and efficient. Came here for an emissions test and vehicle inspection. I was expecting and hour to 2 hour wait but I was in and out under 30 mins. As far as vehicle services they do it all "For everything in, on or under your vehicle." Highly recommended.
Great service, they got me fit in within 10 minutes of calling and the service was completed and I was on my way in 20 minutes. They also had prices that cannot be beat. I Highly Recommend Them, brings back memories of the jingle, "Don't worry it's the Car-X man!" I truly trusted their insight and got the vibe that they are as honest as Abraham Lincoln. Andy and David are truly exemplary employees
They are so friendly! The part I love the most is how honest they are, and how they actually care about you! They treat you like a person with a real life, not just another customer they are trying to sell to. Not to mention they get things done quickly and very well!
Andy is running this shop now. Just met him, but he's legit. Gave me a coupon. Shop is clean looks like he's gonna run it up real nice. Super friendly. He's been doing this since he was a kid. He's old school. Please give him a chance to earn your business
