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.
2024 GMC 3500HD AT4
This review is for a two week old truck. I have been trying to get a 3500HD AT4, gas engine, 8 foot bed, 5th wheel prep, in blue for over a year (almost 2). My dealer finally received an allocation and I was off for the build!! However, when my build order was sent to me the color had defaulted to black (blue was discontinued for 2024) and the only way to change it was to cancel and start over.....so black it is!! The truck is gorgeous and much larger than I thought! I am pleased with both exterior styling and the 2024 interior refesh. My only complaint is the seats, they are a bit firm.....still comfy....but firm. The GM sunroof is small, so small I passed on the option. Mechanically this truck is a pretty sound design. Another 50hp for the 6.6L gas engine would be nice, but 401hp is pretty decent. A PTO offering in the up level trims would be nice, as would a larger/dual fuel tank option is needed (GM is the only one that doesn't offer one), and a factory level in the front, and while I am dreaming a front locking differential. GM could up thier paint game, when approaching 90k I expect better paint. Value wise it is as good if not better than the rest of the over priced trucks on the market. Rumor is 20K per unit on average goes to the UAW pension, that's why your 50k truck costs 70k. In closing I have zero regrets other than the color, but I needed it immediately so here I am.

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.

Awesome experience!
I was looking for a specific Ford Truck, a F350 Diesel. I found one on Cars.com that was at Interstate Ford. I live about 2 hours away from the dealership. I contacted Ryan Huber, one of the AMAZING sales reps there, by email. Ryan emailed me within minutes of my inquiry about the truck I saw and made an appointment with my that day to see the truck. Ryan was great! very low key, no nonsense, and helpful. not only did he show me the truck, he helped me through the purchase, financing, and final delivery, coming in on his day off so i could complete the purchase and pick up my NEW TRUCK! Thank you Ryan!! and Thank you Interstate Ford! You folks know about good customer service, valuing my time, and are extremely helpful and knowledgeable! Ryan, you are the best! if you need a new truck or car, Ryan is your guy!
Truck is a Solid vehicle overall.
Has a really Big feel to it. I currently use mine to pull gooseneck trailer. I haven't had a load yet that I couldn't pull. The downsides to this truck is to me I feel it could get better fuel mileage. Also I had trouble with #4 injector...dealership replaced it. Now my AC doesn't work all the time. Although it sounds like it's blowing it isn't.

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.

Berkenkotter Motors 2015 Toyota Tundra sale
Berkenkotter Motors in Castle Rock, Colorado and Parker are excellent dealers in used car, and truck sales. We have purchased our fourth vehicle (Toyota Tundra Max cab) from them in the last 12 years and love it. Berkenkotter Motors provide awesome, honest, low pressure used car, truck sales. They stand behind their vehicles if you have any trouble in the short term. Although they sell used cars, RV's , boats, and trucks they are checked over and are of great quality. I did get a great trade in on my 2003 Dodge 2500 long bed. Previously we also purchased from them a 2007 Toyota 4runner, and 2007 Toyota corolla. We had only one small service on the 4 runner. While having five lots, they have a lot of cars to choose from and if they don't have what you want they can get it in a short term. Take the time to meet their friendly staff, Dan, Steve, BJ, Alan, Frankie, Wade, jetty, Hanna, etc. We just love them. We got the financing every time we wanted. We currently are looking at RV's for our retirement travels.
Love my GMC HD
I ordered a 2022 3500 SRW Pro LB Double cab 4x4 in silver metallic / blk cloth. Added preferred package; gooseneck pkg; X31; upgraded wheels; camper/Snowplow prep; black steps. Got the 6.6 gas L8T. No start/stop and runs on all 8 cylinders all the time. I Love this truck. Had Rams and Fords in past. This is my first GM truck. I am in my 50s so not a brand thing... just a great truck. It was delivered in June. Truck rides great, tows very well, reciever or gooseneck. Fuel mileage is outstanding! Especially for a 4x4 one ton. I get 16 to 18 highway when not towing. I was shocked by how well it did and impressed with towing mpg as well. I generally tow between 6 and 14,000 lbs. Loads include a Glacier bay catmaran boat, 30' camper, and 3 axle 25' gooseneck. Truck easily handles those loads. The L8T engine is smooth and powerful. The 6L90 Transmission functions perfectly. If something were to happen to this truck I would not hesitate to order an exact replacement. So far very satisfied. MSRP as ordered was $53,945.

We had an excellent experience buying a truck here.
We had an excellent experience buying a truck here. It started with Ali. He helped negotiate extremely well.. He was very personable and eager to meet our requests. Andre was awesome! He was very professional and was able to give us what we wanted. Taelor in financing was great too! Made the document signing very easy and understandable. Last, we can't forget Brian for getting the rims off our trade-in back to us! Thank you to AutoNation on Arapahoe! It was definitely a painless and very smooth transaction.

Great experience with Berkenkotter Rastle Rock.
We had an excellent experience working with Dan & Wade on the purchase of our new vehicle. The sales team helped us through the process and were incredibly patient. Used vehicle prices are out of control and it's comforting to know there are car dealers that go the extra mile. I would rate our buying experience 10/10. We will be back when looking for another vehicle. Give them an opportunity to earn your business!
Excellent vehicle top of line . Fully equipped
Great vehicle. Plenty room inside and back. Really nice interior exactly what I was looking for. All extras heated seats, Starring whell . Sun roof. Has everything. Ream happy with.
