Best experience Buying a car no hype or pressure
Just Bought my first BMW 328i Xdrive and was treated excellent by Veronica and David stepped up and made sure I was taken care of when Veronica was on bed rest , Veronica called and text me from bed rest also. while i waited for a windshield took a little while but they also saw a few things on a used car that they did not have to fix but did and i was amazed that they went above what iI would expect on a used car. I was never pressured and Rami in financing never tried to up-sale a warranty. so with a full tank of fuel we drove back to Iowa VERY HAPPY thank you! :)
Highly recommend salesman Ruben Ibarra excellent s
Excellent service from Raul Ibarra sells man made us feel very comfortable. Highly recommend him does not make you waste time going back and forth to get a lower deal he goes straight to the deal.

Amazing Service Department
Chris Johnson in the service dept. was awesome! I had a major engine problem and talked to Chris who instructed me to bring my car in so he could look at it. To make a long story short, Chris and Hyundai stood behind their product and completely took care of my problem! Can’t say enough good things about Chris and Hyundai! Thank you!

From the first time I set foot on the Buick car lot, Beau
From the first time I set foot on the Buick car lot, Beau set off a great car search experience for me and my family. Not only was he awesome but everyone I met there was warm, friendly and caring. The O'Fallon Buick GMC not only brought back my faith in a car salesperson but also purchasing at a car dealership. From the salesman to the financial department each person took time to make sure you understood exactly what was happening. Hopefully, I want have to purchase another car for a while, but if so, I know where to go.
We love our XT5, it drives great and looks great.

Dodge Durango
Bob Reason did amazing job with helping buy my Dodge Durango. I drove one car and he could see I wasnt happy with, so I asked if there was anything else in my price range he pointed me two others and when I came back from driving the Durango he knew it was it. Very helpful and pleasant.
Worth the money!
I have owned Mercedes GLS, Lincoln Navigator, Infiniti QX80, and now Escalade ESV. The Escalade has been my favorite. I now have 120,000 miles on it and have only had to replace shocks. Electronics work beautifully, it is unbelievably comfortable, and there is nothing like the looks of an Escalade! My only complaint is the well-known 1st to 2nd gear occasional kick from the transmission. Dealer has looked at it multiple times (flushed & reprogrammed) with not much luck. 2WD most of the time and throw it into Auto 4WD when Ohio winters hit and this thing eats snow and grabs the road like you wouldn’t believe. Have never even switched it to 4High or 4Lo. Well done, Cadillac!

Terrific car and experience at Suntrup Volvo
We had a great buying experience at Suntrup Volvo West County. Ken our sales person was terrific and very responsive both to my wife and myself. The review of the car on delivery was excellent and helpful. We love the car and already have taken a few road trips with it.
Great value
The XT5 has met all of our expectations in handling, performance and comfort. The 3.6 engine has excellent mileage and power. Interior is very comfortable and stylish. The XT5 appearance does distinguish itself from a lot of SUV's out there. I bought vehicle from a lease return and it looks like it belongs on the show room floor

Great experience at Carmax at Mid Rivers in St. Louis. We were looking for a low mileage 2014 Toyota RAV4 and we found the SUV we wanted on the lot. In total it was the fastest we have been in and out of a dealership after buying the SUV.
Good interior quality, beefy, spacious and well built.

I had just got this car and it's been to the shop twice, first 2 days I had it I loved it, the performance is great and the interior is amazing! I have the sport utility model and I love all the features and the sound of the xt5!! Over the week my power liftgate stopped working/ would only work at certain times, my check engine light came on reading codes about the camshaft and coolant temp not being high enough. I'm not sure what's going on, this might just be a me problem but over all very nice car, just alot of bells and whistles and specific dealerships to go through if it ever needs repairs.

This is the fourth vehicle that we've purchased from ELCO
This is the fourth vehicle that we've purchased from ELCO Chevrolet, and there is a reason that I returned for my third Tahoe: they're the very best. Three weeks ago, I lost my husband unexpectedly and with two ELCO Chevy's, one 10 yr old Tahoe and a two-year-old Trailblazer that my children didn't want I felt it best to combine the trade-ins and purchase a new Tahoe that will take me another 10 years, providing me not only transportation but the security I need moving forward. The staff at ELCO were respectful, kind, understanding, and efficient. The purchasing experience was excellent from start to finish, and they took every step to make me feel like I was the only person in the dealership those two days. I am very grateful to Mark Gerecke and Branden Nehls for all they did to make the process as easy and comforting as possible given the circumstances. I am an ELCO customer for life.
Gotta get the XT5 Sport.
This is my second XT5. Had a 2017 and never had a problem. Just got my 2023 XT5 Sport, and wow, maybe too much power for a senior citizen, but I love it. A few changes from the 2017, but love the car. I put other vehicles like the Jeep or GMC as beasts, my XT5 is more like a cat, still get where I want to be with luxury.

Over all a great experience
Had a very good experience with Napleton Honda salesman was great also will definitely buy from again. The facility was very nice and located easy to access the interstate from.
My wife and I enjoy our XT4 and we have drive it over
My wife and I enjoy our XT4 and we have drive it over 19,000 miles in 11 months. People complaining about issues apparently didn’t test drive one before they purchased other wise they shouldn’t be complaining. Performance 8 Comfort. 8 Quality. 7 Exterior finish 9 Interior 8 Ride. 7 Quietness. 8 Nimbleness. 8 Handling. 7 Rear seat room 6 Over all for the value it’s a very nice car. The sunroof had a rattle - dealer repaired a loose clip - fixed - - dealership replaced its battery it seemed weak - replaced with a more powerful one. We have at times spent 7-8 hours highway driving found it very comfortable and quiet. Headlights light of the road ahead very good. In all a very good car. Sounds like some owners should have driven one more before purchasing one or maybe purchased a larger model. We have owned many much more expensive vehicles and this one is in the top ones we have owned. We are in our 70’s so its smaller size is great for getting around. We haven’t had any issues like their complaining about. We will purchase another one possibly a 2025 model.

This is my 2nd SRX Performance, unfortunately my first, a 2014, was totaled on a back road here in Southern Lancaster County PA. That car rolled and flipped during the crash that I WALKED AWAY FROM!! Thanks go to all the airbags in the Cadilac!! That wreck convinced my to buy the 2015 I presently own. I currently have over 204,000 miles on my car that I have driven all over the country as a traveling electrician and the dependability of this vehicle has been unmatched from any other vehicle I have owned. That being said, the only thing that has let me down is the CUE screen. Seems as if the screen internally separating was a known issue that GM/Cadillac left us hanging on. It's a very expensive repair from Cadillac but can be fixed if you have the time and mechanical ability fairly inexpensively. I'm sure I have the capability to purchase a new aftermarket screen and repair it, just don't have the time nor the desire at this point to go through all the hassle. Again, Cadillac should have already fixed this problem but unfortunately they ignored it. I'm actually looking for another low mileage SRX to have on standby for when or if my current car fails me.

Always a pleasant experience. I never have any complaints about service or customer service.
Stylish but underpowered
Just bought this car, it's very stylish, kind of small and boxy looking. The seats are very comfortable. Interior refinement is pretty good, it feels like a luxury car on the inside. Rides and handles okay but for the love of god it needs more power, I keep thinking how much better a car this could be with a V6. Oh well, I bought it, I'll have to live with it. I still like the car.

Jennifer Crawford Was The Best!!!
My experience with this dealership was nothing less than wonderful. The entire sales department was nice and respectful. Sales and leasing consultant Jennifer Crawford was the best from the very moment I pulled up to the lot. She’s a sweetheart and made the process so much easier. She went above and beyond to make sure that I was satisfied. I’ll recommend everyone to her from this day forward!!!
The Cadillac Of Compact SUV's
A pleasure to drive. Virtually no turbo-lag, responsive, comfortable and stylish to boot. My Premium Luxury has all the optional packages including massaging seats (great for my wife, who suffers from chronic back issues). Drove many competitors, but none could measure up overall to this SUV.

Having owned 1 srx and 2 xt5. Now an xt4, I think it is the most appealing. My loaded sport has all the luxury and safety features. I drive it in sport for kicks, and 2wd for economy. If you don't need cargo space but like the xt5, go for it! Enjoy!
