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

Five Star Service!
I drove right in, the Service Associate that greeted me was very polite and explained exactly what was going to be done, as I waited for my vehicle he came to check on me and asked if I had any other questions or concerns, it was a great experience and I will certainly be returning to Transwest GMC for all my service needs

Best Carlot in Longmont CO!
I recently purchased a used car from Sprinkler Used Cars, and I couldn't be happier with the experience. The staff was friendly, knowledgeable, and helpful throughout the entire process. They made sure to understand my needs and budget, and found me a car that exceeded my expectations. The price was fair and the car was in excellent condition. I also appreciated the financing options available to me. Overall, I highly recommend Sprinkler Used Cars for anyone in the market for a quality used car. Thank you, Sprinkler, for the exceptional service!

I have enjoyed driving the 2011 Acadia SLT-2 for over 10 years. It is great on the road, especially on long trips, and it's a great vehicle for transporting the grandkids. Our Acadia has been relatively trouble-free. Follow the maintenance schedule and the vehicle will perform admirably for many miles. After 171,000 miles we just upgraded to a 2023 Acadia.

I was here at the dealership a few months ago and I traded in my 2010 challenger on a 2014 challenger. The new one I purchased was an absolute gem. It only had about 600 miles on it. I thought “no way will this get approved” I’ll have to drive two hours back home without the new vehicle. Well I am pleased that I had Vincent and Kurt to help every step of the way. Between the two, they got me the best deal possible and I got exactly what I wanted. Never any pressure at all from anyone. The whole team there was exceptional to work with. I couldn’t have asked for a better car buying experience. Thank you to everyone. I definitely recommend going to Omeara. I will for sure be going back when I need to purchase another vehicle. Bill

I have bought three (some for my kiddos) cars from these guys and each has been a pleasant experience. Always ready to help me find what I am looking for and get me rolling quickly. These guys are the best, that's why I keep coming back. Fast friendly, and knowledgeable service.
Only had car one day but 70 mile trip home most en
Attractive and great performance. Many more toys than our previous car makes it a pleasure to drive. I highly recommend the make and model to any one.

How easy it is to work with Johnson Auto Plaza.
Purchasing my new 2022 GMC Sierra was easy as buying something through the drive-thru. The salesperson, Chris Maneotis was awesome. He explained how my trade-in would go towards the purchase of the new truck and went over the financing and options. I would highly recommend anyone to work with Johnson Auto Plaza.
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?

I always bought the GMC Acadia (4 times) but decided to try the terrain. I absolutely love it and it's a great car for zipping around in town. I would take it for a weekend trip but not on a long trip as it doesn't have a lot of cab room, but for two people it is fine

5 Star Dealership!
Best experience my family and I have ever had at a used car dealership! Staff is very friendly and attentive. They helped us find the perfect vehicle and provided us with an awesome loan through a credit union. We absolutely love our 2018 Dodge Grand Caravan. We will be back for our next purchase. Thanks Sprinkler!

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!

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!

My experience was very professional and l am very thankful l went to Johnson Auto Plaza in Brighton, Colorado. My salesman Mark was very pleasant throughout my buying experience. I will be recommending Johnson Auto Plaza to friends and family.
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.

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.

I saw this car driving by the dealership and automatically was drawn to it because of its color. GMC calls it brown but one print out called it crystal metallic purple. It changes colors depending on the weather. I love the handling, the dash and all the bells and whistles! My grandchildren love how much room that it has!
