Awesome experience.
Awesome experience. The five star rating is too low, I'd give them a 15 star. No high pressure sales. Everyone was so nice and helpful, treated us like royalty. Roberto listened to what we wanted to look at, he went through the inventory, and we found the one we loved.

The car buying experience can be stressful, but Anthony
The car buying experience can be stressful, but Anthony at Echo Park made it relaxed and easy. I was greeted and paired with a salesman right away, was shown exactly what I asked for and felt supported each step of the way. Anthony was personable, knowledgeable, no pressure, and made sure I understood everything throughout the process. I can?t recommend Echo Park and Anthony enough!
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.

Great Customer Service and Sales Team
They did a great job of helping me find the perfect pick up. Levi spent a lot of time helping me. A very good experience. After the sale, I had a small issue with the battery and they swapped it out for a new one, no questions asked. Great dealership!
Overall I am very happy with my new Truck.

"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.

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 wonderful car buying experience
I was very pleased with the vehicle I was able to purchase at Grand Valley Auto Lakewood! I had less than perfect credit after being left carless in my divorce. My friends had recently purchased a car from Mike and Kelley and they assured me I would be treated honestly and fairly. I was very skeptical due to the fact that I had recently been taken advantage of on the purchase of my new TV. They listened to my wants and needs and I left in a car that I both loved and knew would do the job. I would definitely recommend and return for my next vehicle purchase!
Just wondering
Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

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.

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.

My husband and I were so overwhelmed with our car search
My husband and I were so overwhelmed with our car search and were worried coming here may be just one more example of the sleazy used car salesman trope--we could not have been more wrong!! Joseph listened attentively to what mattered most to us in functionality, comfort, and price, and helped us to find many options that would be a good fit for us. We had a list of some we were interested in and he recommended some others that would fit the ticket well. He was so patient and informative as we test drove countless cars! Seriously, this guy is like a walking car encyclopedia! But also, isn't afraid to look something up if he's not sure, which rarely happens. It felt like car shopping with your cool uncle who knows everything about cars and is looking out for you. Can't recommend enough asking for Joseph when you need your next car!! He can pull almost any car from another Autonation location, so it's worth going here to work with him even if it's out of your way or doesn't have the car you think you might want! We wound up not finding our vehicle within the Autonation inventory, but still wanted to go out of our way to leave a review for Joseph because he made that much of an impact! A great ally in the stressful, overwhelming process of a big purchase :)
Amazing Truck
Excellent comfort and very good truck, it is very functional in every way, both for business and for personal, it can be said that I have the 2.7L Turbo engine and I can move up to 11500Lbs already checked by me

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!

Lifelong customer
If I could rate my experience with 100 stars I would! This dealership does not pay on commission which made the whole experience less stressful and they have a great inventory along with a great staff. My husband and I went to this dealership because they had all the vehicles I was interested in test driving. When we arrived we were greeted by Vanessa. Let me tell you how lucky we were to have her. She is so caring, enthusiastic, took pride in her work and was never pushy. Once we narrowed it down to purchasing a 2021 Ford bronco she was very thorough in explaining everthing as we went through the paperwork and options. I feel like I gained a friend after working with Vanessa. Even after I bought the bronco she continued to text me to make sure everything was alright and even mailed us a thank you card, which I greatly appreciated. Then during our purchase, we were blessed with Tyler who jumped in to help. He knew everything about broncos and sat with us for over an hour pointing out the different features and answering my 5 million questions. He also assisted us in getting the ford pass app set up on our phone. I highly recommend this dealership to anyone whether you are interested in buying or still trying to determine what you want to buy! Thank you again to Vanessa and Tyler for all your help, guidance and providing us with outstanding customer service. You have gained a life long customer. Mishala & Steve
