Best buying experience ever!!!!!!!!
I have bought many cars from auto dealers over the years, but i have never been so impressed with the quality of help that I received for my first online, out of state purchase. The outstanding description and the most honest opinion of the vehicle that I received from John Esche made the buying experience a pleasure. They don’t get any better in my opinion. Thank you so much . Don from Ohio

Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

Dropped my truck off to be serviced today. Stephen Mckenzie had my truck ready in less time then I planned and also recommended a few other services that I needed. I was amazed how fast he had me in and out. Completely personal, even walked me out to my truck and started it up.
Overall I am very happy with my new Truck.
Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

Nico, you are the best!
Very helpful, no pressure, great prices and willing to work with you to get the best deal ever!!!! Nico covered all of my concerns and answered all of my questions.
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!

Great experience buying a car is always stressful to me
Great experience buying a car is always stressful to me but great but not pushy!
Like the truck but also disappointed
Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

both Roberson.
both Roberson.and the gentleman in the used car financing were amazing. what used to be a whole day process was done in 3 hours including the test drive. I highly recommend them both for thier professionalism courtesy and above all honesty and desire to fo right by thier customer
Surprised myself and bought a GMC
I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

Simply an excellent automobile shopping experience
Craig Vetti made my car buying experience very pleasant. Craig is very knowledgeable especially when I was not purchasing a Mazda. Will in the credit department was also a pleasure to deal with. Everyone I dealt with Craig,Will,and Hudson who delivered my beautiful new Tahoe was a pleasure to deal with. Thank you so much, and I intend to send future business your way. Joe Joyce

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

"THE" GMC Truck!
I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

The other reviews here are penny ante, very minor stuff.
The other reviews here are penny ante, very minor stuff. I asked Lisandro for an out the door price and I got it fast, with options to help me with financing and shipping. Most other dealers are very slow and never give that price. Performance Mitsubishi's price was $12000 more than advertised. Give both a chance and you will do business with Lisandro. Spend a couple minutes and see. Besides being GREAT to deal with, test drive the Outlander. It drives better than the Rogue and is crazy cheaper than Toyota. It is nicer inside too. Don't buy a turbo gas car. They don't last as long. Buy an Outlander from Lisandro and you will get the deal and be happy with your car.

Exceeded my expectations
I haven't bought a car since 2008 and I have been waiting to buy the Bronco Sport which is a job in itself!!! So I was a little nervous after all the time. My salesman Russ walked me through the purchase with kid gloves. He patiently waited till I was completely comfortable with the terms and most of all never once made me fear of losing the car I wanted. Absolutely no pressure at all and this made my experience pleasant and most of all I grew to trust him like I have known him forever. I am a Real Estate Broker and I know what a Hard Sell is. He treated me as I would a first time homebuyer. Once I was ready came in Orlando to finish the deal. His humor and relationship with Russ made me feel comfortable and secure. Orlando did his job with explaining the Options and was never pushy and enjoyable to work with. The end process is what everyone warns you about. With Orlando he took what I wanted and listened to my concerns and made it work. No I did not buy them All but I took the ones that made since for me. Honestly a pleasure to work with these guys!!! Only four stars for financing/Buying Process as they lowballed my FJ Cruiser. Thats an emotional opinion :)
I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

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

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!
