have purchased 2 pre-owned vehicles from Mayse.
have purchased 2 pre-owned vehicles from Mayse. Live in Kansas City. What I like about them is they had gone thru the vehicles and fixed all the problems before they even sold the vehicle. we settled on the price, and I told them if it was as clean as they said it was, I would take it. both times went down, inspected and less than 2 hours drove off. cannot compline about anything. first car lasted 10 years and had over 275000 miles before I decided, it was time for a different car. 2nd on purchased 3 years ago. driven 50,000 miles no issues.
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.

Purchased a 2024 Ram 2500.
Purchased a 2024 Ram 2500. The sales staff was excellent to work with and very personable. I would recommend doing business here and will try to in the future. I flew there from Nebraska to make this purchase and was nervous. When I got there I soon realized I had made the right choice. Sales personnel were not pushy and very down to earth and didn’t not try to force anything on you that you did not want. After I bought the truck I jumped in it a drove home six hours with no regrets and no issues on the truck I picked.
I have had to of these before and I drive the xxxx
Just what I was looking for and the price was right. The color was the same as the truck I traded in. We have purchased a bumper pull camper and now mountain passes will feel like flat roads!!

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.

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.

Capable truck with the right options
Drove well and plenty of power, the SLT is perfect for us with the 40-20-40 front seat and without the extras that we don't need that are on the Denali.

My husband and I are very satisfied of our experience
My husband and I are very satisfied of our experience trading in our car at this specific location. Andrew is very much helpful. We’re very glad that he was our car dealer/representative. He is very knowledgeable,friendly,polite and thoughtful. Although it took us few hours to close the deal, we didn’t mind about it because we have a very nice dealer. He made sure that my family is comfortable while going through the process and paperwork. He made us feel comfortable and at ease. What I liked most is that he explained everything in details and he answered all our questions or concerns. Also, thank you to his manager/supervisor and others who have helped with the process and paperwork.

EASY TRANSACTION, GOOD TRUCK
I bought a F350 online thru Cory. I bought it unseen, just pictures. I had the truck picked up by a friend and brought to New Hampshire. Truck is in very good shape, and I got it at a great price. Cory was very easy to deal with. Next time I need a truck, I will call him.

I had such a great experience at Chevrolet of Bend!
I had such a great experience at Chevrolet of Bend! From start to finish, everything was smooth and easy. Jonathan Stewart was incredibly personable and made the entire process stress free. He really listened to what I was looking for and never made me feel rushed or pressured. The finance director, Scott Keller, was just as great - friendly, efficient, and transparent about all the details. I appreciated how quick and straightforward the paperwork process was. Overall, it was the easiest and most positive car buying experience I've ever had. Highly recommend this team!

Juan is the Greatest sales person you could ever hope for, he was very patient with us and did everything he could to get us into a New truck for my wife. We did end up purchasing a 2017 Ram 1500 and are very happy with our purchase. Could not have asked for a better place to get a vehicle from
