I finally landed at AutoNation Honda O’Hare—and I’m glad
I finally landed at AutoNation Honda O’Hare—and I’m glad I did. Shoutout to Michael Tiritilli for being the chillest car salesman I’ve ever met. No pressure, no sales pitch that felt like a TED Talk—just good vibes and real talk. Traded in my Jeep (RIP, old friend) and drove off in a shiny new 2025 Honda HR-V with a great APR. Meanwhile, McGrath was out here trying to sell me a car and my own kidneys. Zero stars for them, five stars for Michael and the team at AutoNation!

Van Horn is a Wow!
I dealt with Van Horn on an SUV for about a week. The vibe was so good that I ended up driving 900 miles on a Tuesday to make a purchase with them. I buy a lot of vehicles and I have never seen people stand behind their vehicles with such customer care and loyalty. They will earn your businesses.Very, very impressed and happy with their first class service and amazing warranty. I highly recommend Van Horn Chevrolet and their sales team.

2019 Sierra SLT X31
I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

I purchased a 2022 Santa Cruz last evening from Travis. I had not test driven this model but Travis explained the car facts and answered my questions. On top of that he was able to assist me with taking my new and current cars home (and I live out near the mountain). Financing seemed easy and fair. I have already referred my family members to Travis. Thank you for an easy experience.

General Washington and JR are two top notch people to work with. They made my purchase easy and was fully knowledgeable about the vehicles I looked at. Very easy to work with and I was happy to purchase from Keffer.
Surprised myself and bought a GMC
I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

Great people.
Great people. Did everything possible to make this transaction as painless as possible. Quality vehicles on the lot. Washed truck before delivery. Even filled up the gas tank! Who does that anymore?
Failed transmission and full replacement
We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

Awesome trucks
I've only had this truck for a month and a half and have had no issues. The interior is just plain awesome. I really like the multi function tailgate on this truck, it's very handy loading stuff into the box and the step really helps when you want to climb into the bed. I really like the ride height on the new trucks better than the 2015 Denali I traded in to get this one.

Extremely professional and helpful. Smooth process. From the beginning of our journey, until we bought our car, everyone we talked to was extremely knowledgeable. All of the options on our new trax was explained in detail. Perfect buying experience.
Like the truck but also disappointed
Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

Beautiful Truck
I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

Just bought a new Jeep Wrangler at here! Bruce in Sales did a great job and was easy to work with. He located the exact Jeep that I wanted! It was a smooth and pleasant experience. Steve in Finance was a pleasure to work with as well. I have bought several Jeeps from this dealership before, and they have earned my future business.

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

It was a pleasure working with Shawna in the Service department. She's the best!
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

AS a U.
AS a U.S. Veteran, this is the third new vehicle I have purchased from Tri lakes. The salesman was excellent, courteous, answered questions quickly, always followed up and was very friendly to us. Honesty, courtesy and professional. Why is this important? We live 1.5 hours from the dealership, passing many other dealers who are just not up to the standards of what I consider a fair conversation and deal. We highly recommend them. So, this is not the easiest trek but produces the best results.
"THE" GMC Truck!
I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

The service I had at Royal Cadillac was beyond what I expected. They made up for the mistakes that parts department made. Rather than have me drive all the way back to Tucson, which is an hour and a half from me, they brought the service man to me. Terry was wonderful. He was even able to get my garage opener programmed in my car. I was so thankful.Erin, I’m sure I misspelling his name, on the day All my problems started was patient kind and thoughtful. Jim, The service manager is another one that went beyond requirements. Royal Cadillac is the second Cadillac Dealer I’ve had to deal with. They so deserve five stars +10. It is so much better than the service I received in California. Thank you again. Kathy Brower

Purchased new in October 2024.
Purchased new in October 2024. Total miles driven 9,276. Just completed a 4,734.2 mile trip through 9 states. Just a pleasure to drive. My wife and I were on the road 16 days, with only 8 driving days, longest day was 674 miles. Average driving speed was about 72+ miles per hour. Seat comfort was amazing, no discomfort, great considering having 4 back surgeries. Very solid on the road with little or no driving fatigue. Performance was great. Of the total miles, about 500 were in town driving and 300 miles was in 4x4 in a snow storm coming across Northern Texas in April. Average MPG was 26.4 with my best 500mile drive at 33mpg. The diesel engine is very quiet requiring me to check the tach sometimes to be sure I had pressed the off button. Very quiet on the road as well. This is my first diesel and I would highly recommend it. Plenty of power, great fuel economy, quiet and very responsive when you need that quick acceleration. amazingly nimble for a big SUV. The adaptive cruise works great. My previous GMC was a 2009, 6.2L V8 Yukon XL. I drove that one 140K miles over 14 years with nothing but routine maintenance, a great vehicle as well. Very happy with this 2024
