We own 2 Mercedes-Benz vehicles and bought them at our local Mercedes-Benz of Boerne dealership. We have the cars serviced there as well. The service department has gone above and beyond to help us with our service needs, & specifically with a unique repair today that ensures the safety of the vehicle. Our service managers acted as customer advocates to (1) expedite service once parts arrived so that our daughter could get on the road safely for her return to college, & (2) optimize economizing the repairs. I highly recommend this dealership.

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

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!

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 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. :)

Excellent experience
We bought a 2019Hyundai Elantra at this carmax. It was a very good experience. Staff was helpful but not pushy or aggressive. The fixed price was fair and made the process less stressful. The dealer charges were all reasonable with no ridiculous added charges. Overall an excellent experience.
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!

Awesone Customer service
Customer service was amazing and the process was fast. I just picked out the truck i wanted online and went to sign papers amd drove off. Its that easy, i recommend Carmax to anyone looking to buy a vehicle.
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.

⭐️⭐️⭐️⭐️⭐️ Exceptional Experience at Cavender Cadillac
⭐️⭐️⭐️⭐️⭐️ Exceptional Experience at Cavender Cadillac San Antonio I had an outstanding experience buying my Cadillac LYRIQ from Cavender Cadillac San Antonio, and it truly set the bar for how car buying should be. I initially shopped at Sewell Cadillac, but they were extremely greedy and unwilling to work with me. That’s when I called Martin Vara at Cavender. From the very first conversation, Martin told me Cavender would give me a deal I couldn’t refuse without seeing any other offers—and he absolutely overdelivered. At this point I knew this was my dealership. I didn’t need to go back and forth and shop around because Cavender put their best foot forward from the very beginning. Martin coordinated everything seamlessly. I spoke with the Sales Manager over the phone, we agreed on numbers quickly, and they immediately removed the vehicle from inventory. While I completed my credit application and paperwork online, they had the LYRIQ prepped and ready to go. Martin called to let me know everything was approved and ready for pickup. When I arrived at the dealership, the Cadillac facility was beautiful, and everyone was welcoming and professional. Within five minutes, I met the Sales Manager—super friendly, knowledgeable, and genuinely great to work with. Any last-minute questions were answered clearly and honestly. While I was signing paperwork, Martin took the time to walk my wife through the LYRIQ, explaining all the features and giving her a full introduction to the vehicle. There were zero surprises—the numbers were exactly what we agreed on. From start to finish, I was in and out in about 40 minutes. That’s unheard of these days. This was hands down the best car-buying experience I’ve ever had—from sales, to management, to delivery. If you’re looking for a Cadillac (especially a LYRIQ), do yourself a favor and go straight to Cavender Cadillac San Antonio and ask for Martin Vara.

This place was professional, very courteous and the price was right. I would recommend them to anybody. I live in Austin and drove all the way there for a great deal and I got it! James took my call, and Trent met me on the sales floor. It was a great experience talking to both of them.

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.
