After any serving of a vehicle taking it through your car
After any serving of a vehicle taking it through your car wash before returning to customer. This might encourage more customer loyality. Oil change prices are too expensive. The expertise needed to do that job doesn't equalate to charging that amount.
"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.

Buy your dream ride here!
Great Experience! I personally never heard of this place until I walked in the lot. I found the exact vehicle I have been looking for for years. The place is so unbelievably clean. If you’re looking for a unique ride for your next vehicle start here. Save your time going elsewhere. Gabe and Stefan were absolutely fantastic! I’ll recommend anyone I know to buy their vehicles here.
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

I was here at the dealership a few months ago and I
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.

Austin Ellenberg helped us find the exact Buick Enclave
Austin Ellenberg helped us find the exact Buick Enclave that we wanted. He was very nice to work with and patiently helped us understand all the new features on the 2025 car. His explanations of everything were excellent, and we appreciate his offer to talk with us again about any new questions that we come up with. We also appreciate that he had a new battery installed before we took possession of the car, since the previous extreme cold temperatures had run down the battery while the car was on the lot.

We were traveling through Colorado on vacation and had
We were traveling through Colorado on vacation and had check engine and wrench light come on, on our 2021 Bronco Sport, was going into limp mode. We stopped at Larry H. Miller Ford late afternoon to see if they could diagnose. We’re able to get us in the very next morning to diagnose and get parts ordered. The turbocharger needed replaced which was a special order part 2-3 days. They lined us up with a loner car so we could finish our vacation and had our Bronco Sport all fixed and ready to pick upon our way back through later in the week. The warranty repair work and care of our vehicle was awesome. We did not purchase our vehicle here they just happened to be the closest Ford Dealer so they didn’t have anything to gain by helping us, but went above and beyond to help and get us back on the road, even completed a recall that was needed while it was in the shop. I can’t say enough good about the level of service we received from the dealership and staff. Would definitely recommend Larry H Miller Ford service department and dealership. Highly recommend!!

I bought a used 2024 Gladiator form Christin Collins.
I bought a used 2024 Gladiator form Christin Collins. What a great experience! No pressure, easy to talk with, no hassle, and the rest of the dealer team was super helpful too. If you need a vehicle I highly recommend you see Chris, she will help you find not only Jeeps but any car or truck you'll ever need.
