I purchased my vehicle through Sill-Terhar Lincoln -
I purchased my vehicle through Sill-Terhar Lincoln - Broomfield CO and had an amazing experience working with Anthony and Kelly. This was my first time purchasing a vehicle out of state which was very nerve wracking. Anthony was my eyes and ears throughout the entire process. He was sending me videos of the vehicle and keeping me up to date on the big things. Kelly was absolutely wonderful. With a two-hour time difference, he was still answering my calls and/or text immediately every step of the way! They are a phenomenal team and were a pleasure to do business with. The paperwork and transportation were seamless, and they held my hand throughout the entire process. Huge Thank you to them!
2020 GMC 2500 AT4
This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

I inquired about a Camaro Convertible that had just arrived, Pablo replied and actually sug the car our if the snow and did a complete video walk around. Since I live 400 miles.away and this was exactly the car my wife wanted I was excited to have Pablo helping me. I asked him to look into the price and I had one more to call on. I called back the next morning got the price, made an offer. Unfortunately we where to far apart and the other car sold. My bad luck.
Beautiful truck

Sales and finance teams were extremely flexible and
Sales and finance teams were extremely flexible and attentive, listening to my concerns and working to find solutions. They supported 2 different test drives when I had a concern about a specific driving condition, being extremely flexible working around my schedule. Cam, Austin, and Alec worked together to provide answers to all of my questions regarding financing and extended warranties. When a last minute issue arose on a Friday afternoon, their maintenance department obtained the part and swapped it out on a Saturday morning to allow me to pickup the car that afternoon. Communication was excellent, receiving 2 status updates that morning.
Best truck I've owned yet
What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.

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!

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.

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

Would Highly Recommend!
I just bought a used Jeep Grand Cherokee! and the staff was very negotiable. They weren't pushy or rushing. I would highly recommend this dealership.
Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

Great Place to buy a car
I was in need of a new car . The one i had was bought in 2005 but the year of the car is 2001. I wanted something a bit newer and affordable. I didn't catch the guy's name since my dad was the one who dealt with him first. No pressure at all. He was very helpful. I test drove the car and loved how it drove along with it's a big upgrade to what i had. So decided to buy it. I bought a 2012 Infiniti G25x, leather seats, AWD. front seat heaters, sun roof, backup camera, defrost on the side mirrors and it's a V6. I love it. I highly recommend buying a car here.

Ask for Ray! He's amazing!
After a horrid experience at Greeley Subaru that has us audibly growling at every Subaru we see, we ended up at CarMax Loveland. We both worked with Ray, who is so sweet, chill, and fun to work with. We got my husband set up with a beautiful Kia Soul for the price we wanted. Ray put in for a transfer for the vehicle I wanted and sent my trade in to get appraised. CarMax gave me over $3k more for my car than Greeley Subaru was going to! Ray put up with my impatience over the next few days while my Jeep Renegade was brought up to Loveland (it takes a couple days so they can throughly inspect the vehicles). Ray answered all of my questions timely and professionally. I am telling everyone to go see Ray at CarMax. The business center people were all fun and pleasant to work with and seemed to enjoy working there. This was hands down the easiest, least stressful car buying experience we have ever had.
