Linda is the best! She always gives excellent service. I?m so happy with my Mercedes from Boerne. They always provide a loaner car while my my car is serviced.
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.

If you’re shopping for a car Diamond Motors is the place for you, ask for Rick the entire staff is friendly down to the mechanic . They genuinely help you get into the vehicle you desire not just something to get you off the lot. Rick helped me out prior to me even visiting the lot , he let me know what he could do for me before I came so no time wasted. I sincerely recommend them over a lot of these other places who just want the sale , Diamond Motors cares.

⭐️⭐️⭐️⭐️⭐️ 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.

Great service and customer service.
Great service and customer service. Excellent service experience for my Mercedes-Benz GLC300. Staff were professional, efficient, and communicative. Vehicle was returned clean and running perfectly. Highly satisfied with the service team.
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. :)

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.

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!

I was looking for a Lexus RX350 and found the exact car that I wanted at Autonation. I called Autonation to be sure the car was still available and it was. It took me less than an hour to drive to Autonation and The salesman Maverick already had the car cleaned and gassed up for my test drive and I decided that I wanted to buy the car for my wife?s birthday. In less than two hours the deal was done. Vehicles that I?ve bought in the past has been an all day process but not this time. I was very impressed with what Maverick and Camron did for me to make this vehicle purchase quick and painless. By the way? my wife was very happy with her birthday present!

Cavendar Cadillac’s customer service is unparalleled.
Cavendar Cadillac’s customer service is unparalleled. They make you feel like a close friend or family member throughout your entire deal. The sales team is knowledgeable and not pushy. It is the opposite of a normal sales experience. It is my 3rd purchase (2 with Martin) and my 1st EV (with Eris). Even after the deal was done, Eris has checked on me and helped me figure out all my new features! If you’re on the fence, just go see for yourself. They will work hard to earn AND keep your business.
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.

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 had a great experience buying a new car!
I had a great experience buying a new car! I was incredibly stressed out when I realized that I needed to enter the car buying arena again after 10 years. I was able to send information via email to Roger Salmeron to request the best out the door price and he rose to the challenge. He then introduced me to Willie back in the finance room who worked with me to get the things I wanted for my new cars warranty. If you need a new vehicle I would suggest getting to San Marcos Toyota and asking for Roger!

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.

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!

Called the dealership prior to heading there to ask if the advertised prices on their add was the actual price. I was assured it was and headed that way. I was pleasantly greeted and introduced to Jacob who is very knowledgeable, straight forward, and a master of his craft. Showed us the vehicles we were interested in and explained the differences between them with patients and no presure to purchase and as advertised the price advertised was the price with no hidden fees or unwanted add-ons that jacked up the price. Any extras you get to pick and decide whether to add them or not. For me it was an all around stress free shopping and buying experience.
