Great dependable service.
Great dependable service. Timely manner between appointment time and actual service. Was properly explained everything.
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.

This is the 3rd vehicle I have purchased and currently leasing a new vehicle from Sapaugh. Rich Konold is the best sales consultant. He knows the vehicles and can help you match your wants/needs to the best vehicle for you, and get you the lowest price.
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.

Great experience with Varfe.
Great experience with Varfe. Will recommend someone to come and work with this guy!! Great work
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.

Leon was great to work with, no pressure and left me with the keys to look and start the vehicle. The lot for cars was well spaced out. Was really interested on what I was looking for. A great place to look for your car.
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.

Worked with Tyson on texting. Found just what I was looking for. Went to dealership to look at it and as soon as I walked in he welcomed me using my name. They were very helpful and very knowledgeable. I couldn’t ask for a better experience.

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!

We had Jeffrey Taylor as our salesman and we were blown
We had Jeffrey Taylor as our salesman and we were blown away at just how wonderful of an experience it was. Jeffrey knows vehicles! Every question we had on buying a used vehicle and even specifics on the engine and work done, he knew exactly how to answer or he would obtain the answer for us. As for his customer service, it's outstanding. We didnt feel any pressure at all from him as we have in the past at other dealerships. If we buy another vehicle, Jeffrey is who we will purchase through! Highly recommend him!

I worked with Ron on the purchase of my 2021 Volkswagen
I worked with Ron on the purchase of my 2021 Volkswagen Atlas. He was helpful, straightforward, and got me into the car I wanted. Mark, the gentleman that handles finance, was exceptional and worked diligently to get the sale done in the best way for both the sale and the buyer. They have definitely earned a return customer.

My Husband and I had a great experience trading in two of
My Husband and I had a great experience trading in two of our vehicles for one and the loan process was quick and easy! Justin went above and beyond to make sure we were comfortable with the trade and made sure to give us the best offers he could to make it worth it to us. Being a used car, there were a few minor concerns we had with the vehicle, but he quickly offered to repair as soon as possible. Overall we had a great experience!
