Having owned and driven excellent and exotic automobiles during my 60 years piloting cars, I can report that my experience with AutoNation West has never been disappointing.

Their comment remains true today when they immediately redressed a small clock setting issue following my most recent routine service. Do yourself a favor and put this full service dealership at the top of your list to enjoy a confident buying and service experience.

This truck is exactly what I was looking for! Very well kept and in great condition. Great ride and interior is like new for this 2013 Yukon. All the comfort and space I was looking for to get ready for the winter!

Awesome prices, awesome staff, everybody was friendly and very helpful, was not rushed or pressured

Just trade in my 2015 GMC Denali with 140000 miles on it and still holding strong at trade in best SUV I ever had upgraded to the new 2021 Denali and boy do I love this SUV from comfort to outside design just an amazing new well designed SUV.

My wife and I were looking to replace a vehicle; online browsing led us to several choices from Drive N-Motion. My wife visited the location over lunch one day and met Zach. She left with a strong impression and Zach was quick to address our numerous emails. Throughout our search, Zach was personable and knowledgeable. We set the pace for our car-buying experience; Zach always made himself available but never pushed us to move forward. On numerous occasions, he adjusted his schedule to work with my wife and I. As we narrowed our search, Zach continued to provide us with additional options. Once we had sufficiently narrowed our criteria, Zach even searched Drive N-Motion’s incoming inventory and made available additional vehicles which fit our budget. Zach went above and beyond to serve us. He and Drive N-Motion took the car-buying process and made it as pain free as they were able.

We drove two states over to McKenzie Buick GMC in Milton, FL to meet with Nick and make a purchase on our new Yukon Denali. Customer service was top notch. We were going for their 2019 Yukon Denali to replace a 2008 Tahoe LTZ. We are very pleased with the vehicle. The upgrades are wonderful. Love the cooling seats, the wifi, the HUD and even days after our purchase they have reached out to check on how we were and mailed us a small gift that meant so much. We will definitely use them again if they ever have what we’re looking for on a future purchase. - Brandon Howell 2019 Yukon Denali

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

Chris Whiteside did a fantastic job facilitating my purchase. Chris made it easy and fair to buy this car in a competitive market. I live in Arizona wanted to purchase 2024 Nissan Z. Not only was everyone in my state overcharging. They were all rude and arrogant. As if they were doing my a favor by overcharging for a somewhat limited vehicle. So I bought this car in Colorado. All over the phone. Because Chris always answered my calls and was very respectful. I feel like I made a friend. And believe me, that's hard to say about a car salesman.

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.

Just an amazing experience at Primera Auto. Eric was super nice and got us into a car that fit us perfectly! The paperwork was simple. I felt no pressure to get into a car I didn’t want, not like another car dealership I dealt with earlier. I would definitely recommend Primera Auto to family and friends and I wouldn’t hesitate to look for another vehicle here in the future.

This Yukon is very roomy, comfortable, has tv for my kids. New tires, great condition Best vehicle I have ever owned. I highly recommend it.

I showed up. They had the car outside pulled right up front for me. Cisco greeted me and was friendly all the way through. I drove the car it drives great im a certified mechanic. It is in great condition. I get my tax returns next week. I will be back to buy the car if it's still available l. Based on the way I was treated even if the hyundai is not available which i hope it is but if not I will be back to buy a differnt car from South Creek

I purchased my 2010 Sierra in 20111/2 35,000 miles,l now have 241,000 miles it’s not a work truck other than maintenance repairs it’s been a great truck. I have to say it still runs great,sounds good. I’d buy another one!

I don’t usually write reviews, but Schomp Hyundai in Arvada has earned this one. Over the last few years, this dealership has leased me three vehicles: a 2023 Kona, a 2025 Ioniq 5, and now a brand-new 2026 Ioniq 5. That alone should say something, but the why matters more. When my Kona lease was nearing the end, I fully expected to turn it in and start shopping around. Before I even had the chance, Attila Szabo reached out, not with pressure, not with gimmicks, but with an actual, genuinely great offer on an Ioniq 5. I wasn’t even sure another Ioniq 5 was financially realistic after federal and state rebates… turns out it absolutely was. The deal made so much sense that now we somehow have two Ioniq 5s in the driveway. What really blew me away was the efficiency. Schomp had something like 250 Ioniq 5s in stock, so once I picked the exact one I wanted, the financing process took about 20 minutes. No exaggeration. No drawn-out back room waiting. No “let me talk to my manager” theater. Just clean, fast, respectful execution. Huge credit to Attila and Manuel Ayodele for making it feel effortless. This dealership also backs it up after the sale. The service department has been consistently excellent. I’ve never waited more than an hour for routine maintenance, which feels almost unheard of these days. They respect your time just as much as your business. Schomp Hyundai doesn’t rely on high-pressure tactics or flashy promises. They win by being organized, transparent, well-stocked, and staffed by people who actually follow through. If you’re leasing or buying a Hyundai—especially an EV—this is how it should be done. Highly recommend Schomp Hyundai of Arvada, and especially Attila Szabo and Manuel Ayodele. They’ve earned a repeat customer more than once.

I fell in love with my GMC Terrain when I test drove it and have not lost that loving feeling! I have received tons of compliments on it.

Excellent salesman Alex Pirani Excellent service rep Dan Peterson Very knowledgeable and 100 percent customer service Highly recommend this Toyota dealership Stevenson Toyota Toyota Toyota

I have had this car 5 years 90000 km. No problems so far, it has been exceptionally good. The only money I have spent is gas and oil changes. I. Would buy another one

I went to this dealership because they had a used car that I had found. I had my own financing. My sales representative, Jay, was a very nice. We took the car for a test drive, I noticed the windshield had several chips and one large crack. They agreed to replace the windshield. I found out that they do not negotiate on price, so what you see is what you get. They were a little bit pushy on trying to get me to use their financing even though we declared up front we had our own financing but this is the case at most dealerships. After agreeing to buy the car it took several hours of waiting for them to get the paperwork done. Once the paperwork was done, the signing part was quick. Yay digital signatures! Again, the finance department was pushing their warranty/Gap insurance but my bank has always had a better price on these. I?m not sure where the miscommunication came but my paperwork was not sent to the bank so I had to follow up with them to get it sent over several days later. Once they received the check they washed the car up and we picked it up. As they promised they got the windshield replaced several days later. Overall, if they had another vehicle I wanted to get, I would go back.

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

Foundation Cadillac did it again—and honestly, I’m not surprised! When my 12V battery died on my Cadillac Lyriq, David Hann and his incredible team jumped into action. They did whatever it took to get me back on the road quickly and stress-free. David is truly amazing—always professional, caring, and reliable. If you’re ever in need of service, repairs, or even looking to make a purchase, go to Foundation Cadillac and ask for David. You’ll be in great hands!

I'm 6-4 so I'm looking for a comfortable vehicle that's easy to get in-and-out of plus is high quality. I don't buy new cars and in our 40 years of marriage it's the nicest used car we've purchased.

Monty Mani was our representative for this deal. Monty was awesome and helped guide us through the deal. I would highly recommend Monty if you go to Larry Miller Jerp

I purchased my 2016 GMC Terrain SLT in 2018 as a gently used vehicle with only 21,000 miles on it. I never had issues with it. I kept it regularly serviced and had to replace tires. At now over 93,000 it has been a comfortable and very reliable car. The only feature I wished it had was rear air conditioning. Living here in the SE it gets hot and it takes a “minute” to get the back of the vehicle cooled down. However, I rarely have back seat passengers, and thankfully, the really hot weather lasts only a few months! I have been very pleased with this car and would recommend it to others. I traded it in a week ago for a larger car only because I need the room for a grandchild, and my elderly parents.

Saw this car online and knew it was going to be the one. The car is absolutely beautiful inside and out and even better than it looked in the pictures.

We had the absolute joy of working with T while we bought our vehicle. T went above and beyond in so many ways - by coming in on her day off to help us out, adjusting her schedule to accomodate ours, being open and honest about the vehicle we purchased and the dealership itself - she was able to answer all the questions we had. We even had a small issue (no one could have known at the time of purchase) pop up a week or so after we purchased the vehicle and T was able to get it fixed for us, no problem. And - you know how buying a car usually takes all day? Not here. It took less time than any other place we have bought a vehicle, which is amazing. Thank you, T! You are the best!

I had my 2020 Terrain for 5 years before I had any major issues out of it. My brake booster needed replaced. After about a month of it being out the shop someone hit and totaled it. Very sad day. I love my Terrain

Jeff Gipson & his team were a tremendous help in our purchase of a used car for our daughter at CSU. Jeff eased the challenge of buying a car cross country with all his experience in working with parents & students. He was proactive & responsive, identifying a fantastic & safe used car of high quality while staying within our budget, all over the July 4th weekend. The team's coordination of inspecting & servicing the car, processing paperwork, & final delivery of the car minimized the stress of the buying process. We had peace of mind knowing that such an important decision all the way from Connecticut was handled by a knowledgeable, trustworthy team. We highly recommend Jeff Gipson to any student or parent looking for a car.

Great all around SUV Crossover. Best mileage- 26 Avg 32 Hwy. Very comfortable, multiple positional rear seat makes the most of comfortable seating and cargo space.

Jesse helped me find a great 2009 Lexus and was very accommodating and trustworthy, great man to do business with, couldn’t be happier with how the day went. 10/10 would recommend.

We love our GMC Terrain !! We recently purchased from former Mike Duman in Suffolk, VA which is now Priority Mitsubishi our salesman Mr.Knight is highly recommended He’s a man of God, great respectable person, and very professional!! Whenever you are in the area and you’re looking to purchase a vehicle contact Mr.Mervis Knight !!

Great experience! When I contacted Weld County Garage about a used vehicle, Sales Consultant Miguel Orozco provided exceptional service. Due to my 1.5-hour commute from the WCG location, Miguel provided photos and videos of the vehicle so I could be sure it was worth taking a full day off. I later learned that Miguel had come in on his day off to assist me, a gesture I genuinely appreciate. Having visited numerous dealers in my search, Weld County Garage stood out as the most helpful, professional, and customer-centric. They were not just interested in making a quick sale, but in understanding what I was looking for and finding the right vehicle that fit my needs and those of my family. Unlike many dealerships, WCG encouraged me to take the vehicle to my mechanic for a pre-sale diagnostic check, and all details listed on/about the vehicle were 100% correct. Like many, I have never had a pleasant experience purchasing a used car. However, thanks to Miguel and Craig, the entire process was painless and drama-free, instilling in me a newfound confidence in car buying -- especially with the right dealership staff. Thanks for a great experience, WCG!

great car has everything and then some. lots of seats and 2nd row heated is cool. it could use a little more under storage in the rear compartment and a cover

Jesse made the car buying process quick and easy. I was in and out in an hour and 15 minutes. Highly recommend Jesse and Front Line Auto.

This car is great so far, have twins that require rear facing car seats and there is plenty room in the captains seats for their seats.

We had an excellent experience. Very open negotiations and we came out with a deal we were pleased with.

Have had lots of problems with the wheel sensors. New tires and new sensors and still have the same issue. Shows tire low and it is not. Just car not even two years the air conditioning would not blow out cold air. The compressor in the back went out, need to be replaced. Side car waring lights come on sometimes even though no car anywhere near me. Fold in mirrors are a joke the driver side comes in and out, however the passenger side sticks. Dealer said yeah that happens. This car is garage kept!

Great experience Diana helped me out a lot had an easy first time buyer experience drove of with what I wanted thank you Diana and Ethio Motors.
