Contact soon after first inquiry - still considering Exceptional Motorcar. Next inquiry will be yes or no on purchasing due to rather far from my residence
An overall nice truck but for a person at my size(5,11)
An overall nice truck but for a person at my size(5,11) the mirrors and posts really block the view. My tinted windows really amplify the problem. The hood also takes a bit of room for a short person. Its a comfortable ride and works well in my line of work in excavation. The sound muffler in the hood makes you think something is wrong but apparently its not.

Very kind People and quick responde by their behalf.
Very kind People and quick responde by their behalf. I will recomended to buy from them.
Big Step Up
This is my first HEAVY DUTY truck and my first diesel. I have only had it a week and 3 days but it has already been on the job and been driven 1500 miles. I expected a much rougher ride than the Chevrolet 1/2 ton it replaced but must say I am pleasantly surprised. I compared ride quality to it's main HD competitors and this GMC 3500HD surpasses them. It has far more tech features than should be expected in a base model but I can appreciate the convenience especially for business. I love that it will project driving maps and directions from my iPhone onto its larger screen. I have not yet towed or seriously taxed its payload but the Duramax diesel is something to behold. Averaging 17.9 mpg over 1500 miles. The DEF fill could be a bit more convenient but putting it under the hood does keep DEF away from fuel filling and is not required often enough to be an issue.

Very friendly and efficient service.
Very friendly and efficient service. I am really happy with my new Encore! Ross Dillahunt far exceeds expectations when it comes to knowing the facts, checking the math, and helping with the technology!
Unbelievable towing capacity.
The Denali version is absolutely what we was looking for. Towing capacity is awesome. Has plenty of room in back for kids or cargo. Would recommend this vehicle for anyone who tows trailers. Duramax is what they say it is with Allison transmission best vehicle on the market.

Michelle Deacon is my go-to sales person for all our fleet needs. She's professional, quick to respond, and has taken the time to learn what we need so she doesn't waste my time. I've purchased many vehicles from LaFontaine through Michelle, and the process is fast and easy from the request to delivery with very competitive prices. She goes above and beyond to meet our needs.

My experience with Dave Arbogast Ford was spectacular.
My experience with Dave Arbogast Ford was spectacular. They went above and beyond to service my car. Despite my car still being under warranty, several other Ford dealerships were unwilling to service my vehicle and provide the loaner that is guaranteed under my warranty. When it came to Dave Arbogast coordinating a loaner vehicle, Leah was very accommodating and friendly. The first person I spoke to in the service department was Justin. Each time I called back, he was very pleasant and willing to help. He communicated updates throughout the entire process, and he did an excellent job explaining the situation in a technical way and with layman’s terms. Needless to say, my experience with Dave Arbogast Ford was outstanding and I would highly recommend them for all of your service needs!

I recently purchased a 2022 Nissan Rouge....love it. Josh was wonderful and very helpful as my salesperson. I experienced a disturbing contradiction in my financing that I discovered afterward but contacted Cody, the dealership manager who worked with me to resolve it to my complete satisfaction. Very satisfied with the overall experience and the new ride!!

Dorsch (Ron & Dallas) were a pleasure to deal with when
Dorsch (Ron & Dallas) were a pleasure to deal with when it came to purchasing my vehicle. I never purchased a used car from an out of state dealer that was so far from me. The process can be scary but they provided me with various pictures, videos, and all the information to formulate my decision. I flew in from New York and they arranged to have me picked up from the airport. The negotiation process was pretty simple as well. I drove the car back over 1,000 miles without a hiccup. Great dealer to deal with; 1 would recommend them to anyone.
