When I purchased my dream car Genesis GV70 from this
When I purchased my dream car Genesis GV70 from this dealership I noticed how well kept the service area was. I only take my car here for service because it is professional, clean, organized and the staff is amazing. They do great work and often have you in and out in less time than expected. Josh and Brad have been so helpful. Their knowledge and experience is much appreciated.
Comfortable
Bought this truck used,I love the comfort. I used to have a ranger.I can fit my plywood in the bed and close it.It is a long bed.My 12 foot jon boat fits good,.better than the ranger and more comfortable

Excellent service, fast process, and very friendly staff. Truly a great experience for a new buyer. I do recommend Angie Flamn!
Bought the car CPO in summer 2021 with 38k miles.
Bought the car CPO in summer 2021 with 38k miles. Now being summer 2024 with 90k miles and I’ve mostly had good luck with the car and its components. I have the extended warranty through 100k miles but I feel like all American cars are built to fail after the warranty runs out. Overall great car: I have the 2.0L turbo engine with 9 speed auto and AWD. AWD is great when turned on, grips the road well, and to be honest the 2.0L has a TON of power; way more than you need for a compact SUV! I had a quick issue around 65k miles where the service traction control and stability light came on for 15 minutes. Dismissed itself and haven’t had an issue since. At 75k miles, it was during the winter time, the car would display “park break realized” and “service traction control” when the auto start stop would kick back on (there’s no way to shut off the auto start/stop system). No issues and lights but the messages would pop up and dismiss themselves. Little did I know it was my battery dying and my mechanic said “some wires were loose” and he tightened them up. Haven't had an issue since I got a new battery. Last thing that happens is sometimes when you have Apple CarPlay going and you unplug the phone, the infotainment system will freeze and no Bluetooth, usb, or CarPlay will work for the reming duration of the ride unless you stop the car and let it sit for at least 30 minutes. Simply shutting it off and turning it back on never worked. Overall I give this car a good rating for 0-100k miles. I am pleased with the car but looking for something bigger soon. I think I did overpay a bit for it ($30k for 38k miles) since I got it summer of 2021 when new cars were nonexistent!

Bommarito Nissan Hazelwood Matt Gonzalez
Buying a vehicle from Matt Gonzalez was an awesome experience he is very knowledgeable and patiently answered every question I had about my new Altima in detail I will certainly buy my next new car from Matt Gonzalez
Would buy again!
Just the right size for 2 adults, a child, two large dogs and two large ice chests to head to the boat with all our equipment and food. Hated to see them downsize it in '17. It has had few maintenance issues and they have been reasonable in cost. It has kept it's value over the years.

Above and Beyond Customer Service
This review is in full support of Clement Hyundai – a dealership located in Wentzville, MO – which has shown remarkable, above-and-beyond customer care. At the end of our leasing period for a 2020 Palisade, my wife and I purchased the car outright. The transaction was handled smoothly and thoroughly by salesman Jeremy Null. Following that, our car needed to go through a few inspections for the warranty coverage. In doing that, there was a faulty wiper installed -- requiring the car to go back in to get it fixed. While this could have been a very frustrating experience – as we live more than 30 miles from the dealership – the team at Clement Hyundai went above and beyond for us, recognizing the inconvenience. Especially Jeremy and General Sales Manager Patrick Piper. They picked our vehicle up and delivered a loaner, as well as provided other coupons etc. to make up for the situation. When my wife realized she left my daughter’s dance recital tickets in the glove box, they drove out to our home to deliver them to us. That’s the kind of operation they run: one that has the customer at the center of what they do. I’ve never experienced such superior customer service from any other local dealership – and I’ve owned BMWs, Audis, Toyotas, Hondas, Fords and other makes and models. Clement is a first class operation and should be super high on your consideration list for purchasing a vehicle or getting service.
Love my GMC Terrain!
I fell in love with my GMC Terrain when I test drove it and have not lost that loving feeling! I have received tons of compliments on it.

I always bought the GMC Acadia (4 times) but decided to try the terrain. I absolutely love it and it's a great car for zipping around in town. I would take it for a weekend trip but not on a long trip as it doesn't have a lot of cab room, but for two people it is fine

Great team!
Great team! I Was a walk-in. Friendly helpful staff - went into look at a Canyon. I found the truck online. Salesman TJ helped with locating the truck and brought it up to the showroom. Even washed it prior to me seeing it ! Great financial staff. Quick and easy!! I Will return in the future for more vehicles.
READ PLEASE I love my Terrain.
READ PLEASE I love my Terrain. DO NOT get the 1.5 L. My engine has barely made it over 100,000 I have had $6k of repairs in less than a year. Things keep going wrong now. I had NO issues before. Catalytic converter went out 75-85k miles. My turbo was just replaced. Just beware of this type of engine… every mechanic that worked on it shared this is not uncommon for this type. I would definitely get another terrain but not the 1.5!

My Work horse.
I brought this truck in 2019. I kept taking it back to the dealership to get tweaked several times. Once it was figured out, never got any problems ever again. A little weak on the power side, but, other than that, its a magnificent vehicle. A total work horse. Great on gas. It is totally worth it.

I have owned my Terrain for 3 months now, and am absolutely in love with it. Super smooth, great pick up, and I get a lot of complements on both the exterior and interior design. I average 26.3 MPG city and highway combined, which is not bad considering I live in Florida so my AC is never off in the car.

Good car only some issues
Have had lots of problems with the wheel sensors. New tires and new sensors and still have the same issue. Shows tire low and it is not. Just car not even two years the air conditioning would not blow out cold air. The compressor in the back went out, need to be replaced. Side car waring lights come on sometimes even though no car anywhere near me. Fold in mirrors are a joke the driver side comes in and out, however the passenger side sticks. Dealer said yeah that happens. This car is garage kept!

Engine light came on, rough shifting, Adam in Service dept fit my truck in for diagnostics within a week. Tech found bad coil, replaced and repaired, also suggested new wires and battery was needing to be replace really low crank, all work completed and again on the road after 310,000 miles. I have had only good experiences with the service department staff and techs. Sometimes it cost some money but its a machine and if you take care or it, it will last.
Its a decent car, but on a car frame.
