Jose was assigned to help me. He was very helpful and knowledgeable. I very much wanted to do business with him but they didn't have the exact car I was looking for.

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.

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.

My experience with Sewell dealership and especially my
My experience with Sewell dealership and especially my sales associate, Luis Barboza has been nothing but positive and great. Luis is extremely knowledgeable and patient with any questions you may have. I've now purchased two cars from Batchelor/Sewell Cadillac and only returned to this dealership because of the most professional and courteous experience I had. Six months after my first purchase (and several times inbetween) I was able to call Luis on his cell he provided and he was as happy to assist me as he was when he sold me the first car. The service department's employees and very helpful and accommodating. They have a BEAUTIFUL lobby with refreshments. This dealership must have high standards for it's employees and they all seem to step up to it.
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!

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. :)

Great experience
I’ve traded two vehicles with Carmax in San Antonio and I must say I’m very impressed with their customer service and their time that they give to the consumers. Patrick Burrows has been an amazing sales associates and I would recommend him to anyone that is wanting to trade in their 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.

Once we had an appointment, we had a smooth experience. The wait times can be very long, so make sure you have one. Jaxon took great care of us and communicated appropriately. The financing was easy and a very competitive rate. Everyone we dealt with was friendly. After we completed all of the paperwork, the wait was a bit long to drive out the door, but overall, I would buy from CarMax again and recommend it!

I bought a 2002 C 5 Corvette, and it had the slave
I bought a 2002 C 5 Corvette, and it had the slave cylinder manual transmission problem which is endemic to the C 5, unhappy with the Chevy Dealer, I went to Jordan knowing they sold many sports cars. Well, Chris Hayson, the service manager, replaced the main clutch cylinder and then concluded it was the slave. He recommended I got to THE C 5 expert, another repair shop. He arranged for my car to be transported and did not mark up th cost of that transport. The second shop specialized in C5 repair and finally my car was fixed. This would not have happened if Chris had not directed me to OK Lethal Performance, thank you Chris!!!!!!!!

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

My 2016 GMC Sierra 1500 SLT All Terrain - Love it!
I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

2012 Ford Edge battery died
My battery died on 410 and Evers shopping center parking lot. AAA came and jumped and gave me a printout and said it was the battery. I had already called Josh Hammond and Jose Rico and said I would be coming. When I arrived they took my car and I had a new battery in less then 45 minutes. The whole experience only took less then 3 hrs and than included an hour wait for AAA. My sister and I were on our way quickly.
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!

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.
