Truly unforgettable.
Truly unforgettable. Nothing else with 25 word or more comes to mind!!! Seriously. I am trying but my mind is blank, I thing they called aging.
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!

I’ve had a fantastic experience with this dealership.
I’ve had a fantastic experience with this dealership. I’ve purchased four vehicles from them, and each one has been great. The person who helped us this time was Dj, and he was exceptional from the moment we met. The car is beautiful, and I’ve never had any issues with any of the cars I’ve purchased here. The customer service is always amazing.

Recently I had to get a newer car and believe me I was
Recently I had to get a newer car and believe me I was stressed because of the situation but when I went to CarMax which this is my second car from them it was once again amazing to work with them! I had the pleasure of working with 2 amazing sales associates. Helen Mayo who was my main sales associate and Cheyeene Toliver who helped out my wife and myself when Helen was off! They both were very kind and helpful and made the process an ease! I was thinking of other options but since they were amazing I went with them instead if your looking for a car I highly recommend you ask for either of these two women they are a great help!
I bought this after going to the dealer just to look at
I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

2022 GMC Sierra SLT 3.0 Duramax
My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Excellent Service
Arman was amazing to work with. I bought the truck without seeing it person and he provided accurate information. He was very patient and easy to work with. Absolutely no pressure to purchase. The vehicle was quickly shipped across the country and arrived as represented. I am very happy with the purchase and would strongly recommend this dealer to anyone looking for a used vehicle.
Most expensive auto I've ever owned.
Great performance, hard to clean, everything, I expected. Getting lots of compliments and head turning. Stomping with thee BIG DAWGS!!!! Good gas mileage on highway.

Good afternoon everyone, yes, I’m a lady and I’m an owner
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

Got an amazing deal from a good car dealer!
Leo at Pro X motors was amazing. I got a very good deal on a decent 2016 X3. Leo was a pleasure to work with, worked hard to get the deal done and I left with the car I wanted for a very good price. I would recommend Pro X Motors to anyone looking for a competitively pre-owned vehicle. Thank you very much!!

The experience was Great!
The experience was Great! Mr Lozano is a great salesman, he helped me with all my questions, all the process was very smooth and simple, all the team is great from Lozano, Tony and Yuri great people, I?ll comeback to do more business with them
Pleased that I made this purchase
Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Great truck to own.
Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

I own a 2023 Sierra 1500 Elevation equipped with the 2.
I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

had a great Experian's with mo very easy to work with very happy with my transaction at car lux
Exceptional truck with one annoying detail.
I truly enjoy every aspect of this vehicle except for the fact that to have my text messages displayed on the screen I have to use a cord and cord my phone into the vehicle. I can Bluetooth phone calls But I cannot get any messages to display without using a cord. For the truck being a 2019 and the price point of it that is absolutely absurd. Other radios that GMCsells has this feature. This truck does not.

I felt they were really looking out for me.
My salesman was Mason. He is new to car sales and I had the privilege of being his first sale. He was very attentive. Didn't pressure me at all. Took time to help me find what I needed. Me being a single mom, his manager Julio understood my budget and circumstance. Everyone was great. I'll tell all my friends about them.
