New and used 2026 GMC Sierra 1500 trucks for sale near Stonegate, CO

Quick & Excellent Service! The technician called us with all of the information we needed and provided video of all repairs. They were very friendly and quick turnaround with our maintenance.

Easy purchase experience, would recommend to anyone looking for a new car. Everyone there was friendly and made the whole process as smooth as possible

I?m not sure how I didn?t notice the air compressor during the test drive but regardless, I bought the car and I do love it so far! To be fair Alex did mention a noise from the AC but again I didn?t hear it during the test drive.

A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

Great service department! Greg was great to work with. Very knowledgeable and great communication. Thanks

It was such a good truck honstly the greatest thing I have ever drove in my entire life I am so happy that I have been blessed with this being my first ever car

We saw the car online a couple days before we could get over for a test drive. We scheduled the drive and the car was ready when we got there. We moved forward with the purchase and were pretty quickly out the door. The car was extremely clean for a 7 year old car, and all the vehicles on the lot looked clean. Friendly sales and finance staff.

Rafael H was very attentive to what we were looking for in a clean used diesel p up . His assistance in our purchase with our purchase was very good . professional, not pushy Gerald & Kay Schreiber

Amazing courtesy and respect from a used car dealer. They honored a price I saw on the internet the day before, even thought the sticker was higher when I came in. Professional, polite, knowledgeable and a very efficient buying process. The used warranty they sell is outstanding and their no-document financing is second to none. I was just blown away on how great everything was.

The service was top-notch. I had a broken mirror and worked with Greg Mudd, who found me a great deal on a mirror, painted it, and installed it, saving me about $350. He was incredibly kind and responsive. It was a great repair experience when I had been anticipating a stressful one.

Jay quickly found the car I looked at online. He was able to quickly get use in and out of the dealership all in the same night.

DJ was my salesman and he did an amazing job! I highly recommend going to Alpine Buick. The Facility is beautifully represented. Always eager to help.

Tonya, Nathan and others have been terrific through the process towards purchasing my new Ford Escape Hybrid. Thank you. Tonya has truly been one of the absolute best vehicle sales representatives that I have ever had helping/taking me through a new vehicle purchase. A big thank you, to you Tonya, for all you continue to do. Working with you is absolutely the best! Thank you!

Recently purchased a vehicle, and was pleased with customer service and straight forward pricing discussions. Our sales consultant, Starlynn and sales manager Tyler were great to work with. Thank you for such a positive experience.

We love the car that we purchased. Our salesperson was easy to work with. We were cash buyers and the finance department handled that well. The only issue is that the car had received a minor repair in the rear fender and during the repair, the dealership failed to reconnect the tail light.

Everyone was professional and no pressure sales. A number very no nonsense dealership. I would go back to purchase again and would recommend to friends to go to Trans West GMC.

The buying experience was pretty seamless. I approached them and asked questions. I liked the information they gave and moved forward with the purchase. I was able to drive the vehicle off the lot.

Purchasing a vehicle can be very stressful, we did not get that while discussing the potential purchase of a new vehicle. Jovanni was very patient with all of our questions.

I really appreciated the free service for my first time in with our new car.

Everyone from the sales rep., sales manager, finance manager and shop team worked to make my experience simple and left a lasting impression. I will absolutely recommend this dealership to anyone in the market for a vehicle.

My experience with Castlerock Chevrolet since 2020 one of the best. I appreciate their customer satisfaction. Puts their customers first. My car engine almost destroyed by an oil change of a place I used to get by cheaper but no more. Thank u again.

Pleasant and friendly We were treated with respect and kindness Would buy another car from this dealership and sales Person. Our last three cars were purchased from this dealership and we will happily do that again next time

We had a great experience with this dealership! I highly recommend using Jeremy Tabangay as your salesman. He was very polite, and wasn't aggressive in his sales tactics. He really made you feel like you weren't just a number to him. He also did a follow up after we purchased, just to make sure that everything was going well. I would also like to give Matt (finance department) a good review. He was fun to work with on the financing of our vehicle, and didn't pressure us into buying any add ons. He was also very quick in getting all the paper work filled out. We really enjoyed our entire visit there. I would use this dealership again in the future. Especially, if I was working with both of them.
