I've been working with Cary and Jesse at Mankato Motors
I've been working with Cary and Jesse at Mankato Motors for several years now. There is zero pressure, and the staff advocate for the buyer. If you're not completely satisfied with the entire car buying process they will go above and beyond to ensure you are. It's a completely different car buying experience at Mankato motors!
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.

Friendly customer service for a dealership, they
Friendly customer service for a dealership, they definitely have that Southern Charm to them. They also have a great selection of vehicles with good pricing, and they arre constantly updating their inventory and you do not feel pressured by them to buy a car from them. The buying process through them is typical of any dealership, but again their friendly atmosphere beats other dealerships within the city limits as well as their pricing when compared to other Chevrolet shops. They also offered me two free oil changes and tire rotations as well as $500 gift card as I went during a holiday weekend, so I would recommend others to ask them for any special promotions or checkout their website. Definitely recommending them to my friends and family.
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.

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
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.

Best dealership buying experience I’ve had.
Best dealership buying experience I’ve had. They got me the deal I wanted and didn’t waste time with back and forth to the managers office. Aimen worked with me on the phone initially since I don’t live nearby and we got reached an agreement on a deal. Aimen, Tomas and Rebecca we very nice, made it go easy. I drove off with my new car and a big grin on my face!! Thanks to the crew at Ron Tonkin Kia!!
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.

Immediate response.
Immediate response. Made an appointment to see the vehicle. Unfortunately, it sold before I arrived. However, the salesman did not make me drive over an hour to get there to find out it was gone. He called and texted to save me the trip. Really appreciate his respect of my time.

I will never buy a GMC from anywhere else. The dealership and people are real and not fake flashy like others. I drive further to get my vehicle serviced there over Jerry Seiner because of the quality, timeliness and communication from the staff.

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.
