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.
One very awesome vehicle.

An excellent experience all around.
An excellent experience all around. The sales person was fabulous. Now the downsides: (1) From the purchase quote to finance ... like most dealers, a long list of add-ins one would have though were included in the quote; and (2) the car itself has a major, serious issue. I suspect there will be some serious accidents in the future forcing GMC to address the matter.
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

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!
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.

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.

This is the Dealership!
I toggled between 4&5 stars and I landed on 5 (which is hard to do with me)and I will tell you why.I started out with BMotors over a month ago looking at one particular 5th wheel and after it had been listed that it had some things that worked it actually didnt but well my son was a used car dealer for many years and this was the reason I asked for it to be checked.I know how things work in used vehicles its not always obvious even to the dealerships. They could have sold me it as it was but they were 100% honest and said they needed to put me in another trailer.This is the most important aspect of a dealership really. You get what they are saying! This new 5th wheel is more then double the price but its more then worth it and I am satisfied with it They did good by me and in house financed me on top of it. Bret was amazing and answered every time I text him a question or concern. When I was ready to haul this giant 5th wheel for the very first time with a truck I just purchased they actually had their service guy (and another employee follow)drive about 6 miles with me to get me out of the city and show me how to make the turns and show me how to use the brake system on the trailer.This is above and beyond!! This Yall is a 5 star Dealership!!! I highly recommend Berkenkotter!! Go see Bret, Alen or Any of the Guys they eill hook you up!
Overall Great Truck
I bought mine in 2017, 2nd owner. It had 36,000 miles on it when I bought it, getting ready to turn a 100,000 miles, and the only thing I've had to do to it, is replace the Def heater, other than that, it's been a great truck. 👍

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

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.

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.

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.

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.
