My wife and I experienced a serious overheating problem
My wife and I experienced a serious overheating problem in our Santa Fe while driving from our home in Kansas City to Chicago. We found Kunes Hyundai online and were blown away by the superior service they offered. Kyle served as our service advisor, and he went above and beyond to take care of us. He patiently explained the problem, told us they had to order a part, and promised the vehicle would be done by Tuesday. When I left the facility, Kyle said he was on the phone trying to work a little magic to get the part sooner. I don't know who he called or what he said, but he worked the magic. The part came on Monday, and they had the Santa Fe fixed and back to us a day ahead of schedule! That was tremendous. We were already sold on the Hyundai, but this experience reminded us again of why we are on our third vehicle. The level of customer care is off the charts at Hyundai. And Kyle is the best service advisor we've ever had. The repairs fixed the problem and got us safely back home to Kansas City. I would gladly recommend Kunes Hyundai without hesitation. They are a five-star dealership! Check them out. You won't be disappointed! Ray Pritchard Shawnee, Kansas
Best vehicle Acura has made in last 15 years.
Best vehicle Acura has made in last 15 years. Test drive an RDX Advance SHAWD package on sport mode for 15-20 mins and you’ll be sold. Beautiful airy cabin with pano, and the ELS sound system is killer! 2.0 turbo engine + 10 speed trans are bulletproof. Have my RDX Advance for 2 years now and will enjoy it for at least another 5 years. These are made to last, much like my 2006 TL that I have for over a decade, with 200k+ troublefree miles on the clock.

Love this car!
I absolutely love this car. I've taken it on several 500 mile trips and it's by far the most comfortable car I've ridden in. One component many reviews do not mention is the stereo system. I have the A-SPEC, which comes with 16 speakers. It was an important reason for me choosing the vehicle, along with the A-SPEC blue pearl color. The stereo system sounds incredibly accurate and by far the best stereo I've heard in a vehicle. It could use a little more low end power to hit low end notes, yet I'm still impressed with it every time I listen to it. And it's good at replicating sound in all genres. Any track sounds good and tuned perfectly! My back has been a struggle the last couple of years and it's one of the reasons I bought the car as well. The seats are extremely comfortable and adjustable. I run hot and the ventilated seats aren't strong, but do make all the difference to keep me cool and dry. The cornering is impressive for an SUV. The torque vectoring clearly pushes you in the turns and helps you turn; very impressive system and makes it very fun to drive. We have some extremely bad roads in the Midwest and it rides better than my other vehicles (2007 TL and 2000 Camaro), but I suppose it could be a little smoother according to some people. I have no complaints with ride quality. Another great thing about the vehicle is how easy driving long distances is. With the adaptive cruise control and lane keep assist, I don't think I could go without it. I haven't driven a lot of vehicles with this system, but I have no complaints with it; it greatly reduces driver fatigue. I drove 10 hours home when I picked it up, and felt great after. Other vehicles definitely make that a struggle. What many people have complaints with is the touch pad for the infotainment system. Once I used it a few times, I got used to it. It seems cumbersome, but Acura designed it this way to keep your eyes on the road. When you realize this, you'll notice how that is true; it does keep your eyes on the road, and I'm satisfied with it. The interior likely isn't the best in class, but there certainly isn't anything wrong with it and I do find it attractive. As mentioned earlier, the A-SPEC blue pearl is quite stunning. I like all the colors, so you can't go wrong with any color, but do check out the blue and red in person; they're my favorite colors. The overall design of the vehicle is one of my modern-day favorites. The panoramic sunroof is nice and worth mentioning. I've heard people complain about the interior noise, but I have no complaints, even if I'm doing 80. Maybe there are other cars that are quieter, but I haven't ridden in one. Hopefully my review helps you with your decision. I love cars and look forward to driving it every time I get in the car. I don't see myself ever regretting the purchase other than the mpg. Just like most cars, the faster you go the worse it gets. It gets about 24 when I was doing 75 for 400 miles. If you start pushing 80, it can really plummet. I haven't taken many trips at 60mph, but it can get 26 @ 60mph for sure. I'd say it can do 27 at 55 mph, but generally 65 is the speed limit in my state. 21mpg has been the consistent number for me in the city. So the advertised mpg from Acura is accurate.

A dealership you can trust
I was looking for a specific car that was at this CarMax. Problem was that I live in Minnesota, not Chicago and would have to traveling a great distance for a car I had not seen other than in pics, potentially risking wasting a great deal of time and money. I had to trust Jonathan, my salesman, to tell me the condition of the car where the pics could not. He was completely honest and the car was exactly what he said it was. Between Jonathan and Adam, the sales manager i was able to close the deal and drive back to home within an hour. I am completely pleased with the car and 100% satisfied with the dealership. I guess you can trust a car dealership. I did and they did not let me down. Thanks guys.
I love my new car

The service experience with Biggers Chevrolet was
The service experience with Biggers Chevrolet was excellent, as always, this time for a brake job. It took a little longer than expected because the replacement process was apparently more detailed since it was a Buick LaCrosse. However, the service staff kept me informed and out the door in a timely fashion. Even though my vehicle is not a Chevy, I come to Biggers for repairs/service due to the sales and service trust that has been built up over multiple decades. Thank you.
well equipped, well priced and an enjoyable drive.
4 moths and 4000 miles, a few rattles have developed, nothing significant, I got used to the touchpad interface and find it to be "just fine" as I typically use CarPlay and do most of my audio control from the steering wheel. The car is peppy, comfy and the audio system is STELLAR.

Sleek and sporty design - turbo charged engine, all wheel drive. Plenty of leg room, rear seats fold all the way down for extra capacity and I absolutely love the black 20in wheels!

I purchased a used Acura MDX from a private sale and took
I purchased a used Acura MDX from a private sale and took it to Acura Westmont for an inspection. Their service team was able to give me a same day inspection appointment when I called to inquire. Carlos and his team of mechanics were very thorough. I will definitely come back when I need to replace the rotors and brake pads on my MDX. Friendly service always makes me a repeat customer.
