New and used 2025 GMC Sierra 3500 trucks for sale near Castle Pines, CO

Great experience buying a new vehicle. Would purchase from again. They have a great selection of vehicles to choose from. This is a first class car dealership.

This dealership was amazing and I highly recommend. When purchasing my new truck, they worked with me to find a price that worked for the both of us. Then when I was an idiot and did not see hail damage due to frost, they further helped by paying for half of the hail damage repair. 5 stars is too low. Eric was awesome and all the managers were amazing. Can’t speak highly enough.

Friendly and knowledgeable staff. Thank you for your help and we love our new car!

Found a desk area with electrical outlet the chairs were kind of old and banged up, and it was kind of in the vending area. Wi-Fi was good for working, but the coffee area was all out of packets for coffee. Good service and they got me out quickly through the process for an oil change the first one on my vehicle and the first service at that location. It was good the The cut customer service was good

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

Looked for a low mileage Acura TLX or TSX for six months and I found this car near me. It was nicely detailed and looked well cared for from the posting on Cars dot com. The sales rep called me very soon after my initial query. The entire buying process took an effortless one hour and I was on my way with the beauty,

Great working with Zack and the staff Got to drive several trucks till I found the one I wanted. Got a fair trade and a fair price

Great experience. Matt and Tony were great to work with. No high pressure stuff and pushing extras

Great car buying experience. Friendly, knowledgeable, no pressure salesman Kyle Berry. One minor problem was handled quickly and professionally with no hassle. Go see Kyle.

Joey was great service manager...car service correct and prompt...very positive experience. Car was returned clean and with a full service report. Highly recommend dealership.

Craig was straight forward and honest we couldn't be happier :-) Went to others and felt different. He answered all our questions. Ask for Craig like the list!

Matt our salesman was awesome and listened to exactly what we needed along with Tony in finance we walked out with what we needed at the monthly price we asked to be at.

Austen is knowledgeable, efficient and friendly. I love that the tech sends you a video of your vehicle and what he?s working on. And the best of all is that they got me out in a timely manner

Rafeal was my contact there and he was great. He went above and beyond to communicate share photos and video and was very transparent. As a matter of fact the whole process and everyone was easy to work with. Not the dealer where sale and sale manager go back and forth to do some crazy negotiating. Open transparent and fair dealing. Rafeal was an advocate throughout and in and out with anew car well less than an hr after trade in paperwork

Shortline was a great experience buying a new truck. They were up front and explained all options and answered all my questions. Proce was fair for the market and no hidden costs! Very happy wity my experience and will recommend to anyone!

Jenny Rose is the best service advisor that we?ve ever had. She made sure that all repairs were completed thoroughly and quickly. We will continue to get our Tahoe serviced here.

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

Went above and beyond all expectations! The team is very responsive and helpful, all of our questions were answered in a very professional manner. I would definitely recommend this place to anyone who asks.

Gregory at Castle Chevy GMC is the automotive wizard we all need! When my wife’s 2023 GMC Yukon XL needed some TLC, Gregory didn’t just fix the issue—he played detective, keeping it an extra day to crack the case like a vehicular Sherlock. And as if that wasn’t enough, he sprinkled some magic dust on a couple of minor, non-essential fixes that were the cherry on top of this service sundae. Professional, communicative, and an absolute delight to work with, Gregory’s the guy who makes you wonder why all car repairs can’t be this fun. Highly recommend him and the Castle Chevy GMC crew for service that’s smoother than a Yukon on cruise control!

Bought a sierra 2023 for my business. The salesmens knowledge was excellent, process through finance was seemless and price was very fair! We appreciate a good dealership experience!
