Their customer service is amazing, as they have dedicated staff who are pleasant to work with and are concerned about getting the job done right the first time. Their business sends out occasional coupons for discounted rates, which also adds to the value of their work. They are a 5 Star business!

Went here a few years ago and gave a bad review. I now see that they have had it removed somehow. I…read morewill now replace my previous review: Took my 1991 Cadillac here as it was running rough. Service manager said he could get her running good again. I felt pretty good about Carz R Us at that point. Left the car there around 830 AM. Didn't hear anything for awhile but got a call around 230 PM. They wanted me to approve ANOTHER $100 for diagnostic service. I wasn't aware of the first $100 fee. In all my years of dealing with automotive services I've never been charged diagnostic fees. I told them to cancel any more fees and I'll be down to pick it up. When I got there they told me that they were very busy and didn't get to my car right away. It was then that I realized that I'm not sure they even got to it. When the person drove my car out he was visibly pissed and came roaring around the corner and slammed the brakes then slammed the door. I'm sure they were counting on soaking me for more $$$. I took the car to a different local mechanic and he fixed the problem in less than an hour for $75 and zero diagnostic fees. Thank goodness I didn't let Carz R Us keep my car. Buyer beware!

From the owner: In November 2008, the Aukes family purchased their first location — a building that housed an auto…read morerepair shop, restaurant, and salon — and officially opened Carz R Us on January 22, 2009. About a year and a half later, we learned the building would be demolished due to the Ralston Road expansion. It was an unexpected challenge, but we turned it into an opportunity — building a brand-new facility at the corner of Routes 173 and 251. That bold move became the foundation of the Carz R Us you know today. Now, we’re excited to continue growing with the addition of our new second location at 7800 N 2nd Street in Machesney Park — formerly Ernie’s Auto Service. We’re honored to welcome Ernie’s longtime customers into the Carz R Us family and look forward to providing the same trusted, quality care you’ve come to expect, backed by our expanded team and services. At Carz R Us, our focus is on transparency, trust, and relationships — with digital inspections, an educational (not pushy) approach, and the convenience of shuttle service, complimentary loaner cars, and vehicle pickup. We take pride in serving our community and supporting local schools and organizations. We can’t wait to serve you — whether you’ve been with us for years or are joining us for the first time.

Asked owner to give me an estimate to replace a side view mirror assembly. He needed to get a price on it and promised to call me with the quote. I had barely returned home and was called with his quote. WOW! That was fast. The quote was significantly less than another repair facility. We tentatively set up an appointment for the end of the week. (See my Tip) Asked owner to quote additional work and had his quote in less than 5 minutes. Set appointment for next week.. Following his inspection he informed me that I did not need parts and service that another facility said I needed. According to his quote for the work, comparing the same items to another auto service facility's quote, I will be saving almost 1/4 of the price plus approximately $200 on the parts and labor I did not need! Well satisfied with the responsiveness, professionalism and honesty of the owner, as well as, the work performed. Especially noteworthy are the prices - SIGNIFICANTLY LOWER than the "chain" shops. This business is the real deal. If you need work, get a quote here and give it a try. Betcha you'll be glad you did.
