Most dependable truck i ever owned.
This truck is a beast, but with the Duramax diesel engine, its fuel efficient as well. my best average is 21 mpg which is insane for a truck this size.

Very happy customer - I highly recommend Snell
I would highly recommend Snell's auto due to great customer service - including professional, friendly, knowledgeable, and very helpful staff. Specifically, Emily Brennan and Jackie Taylor who both listened to my needs, and helped steer me away from making the wrong choice (I was looking for a "beater" truck and was prepared to spend up to about $10,000 - and I had found one online which was there when I got there, but upon seeing it, I quickly realized it was not in good condition and it wasn't the truck for me). Emily helped me talk through xxxxxxand con's of moving into a higher price range (up to $21k) and she recommended the truck that I ultimately bought (a 2012 Ram in great condition with 125k miles) and I couldn't be happier. It's everything I wanted and more, and I feel like it was a fantastic bargain. I felt valued as a customer, and I've never had a better vehicle shopping experience. They even did the license plate, title, tags, etc. all right there - I didn't even have to go to a notary. Thank you Snell - keep up the great work!
Loved the Duramax Diesel and an incredible truck
Incredible truck. Wanted to trade it in for a 2020 same truck but unfortunately the interior for this year hasn't been updated. Supposed to next year. Will check in then. Would never consider a Ford or Dodge over this powerhouse.

So happy with the service at 21st century auto
We want everyone to know if you are in the market to buy a vehicle be sure to go by 21st century auto sales, in blackfoot, idaho. They are so honest and friendly. With no pressure. They explained everything when we had questions on the pricing. We bought a 2019 1500 GMC pickup and are very happy with it.

It was okay.
It was okay. I hadn’t bought a vehicle for a while and they continued to hand me off to different sales person which was different. In the past once you got with someone they stayed with you during the entire experience. We were a thousand dollars apart on making a deal and we could not overcome that. So we made no deal.

Love A&G Auto sales!
I bought a 2008 Cadillac DTS from Tony about a month ago. I've always wanted a caddy but couldn't justify today's prices for new. I knew it was a risk buying a 15 year old car, but I am so glad I did. The car is beautiful,drives like a cloud. There were a couple minor problems with it, but all I did was call Tony and he took care of every problem, no hard time or anything. Very friendly and laid back guy. I definitely would buy another car from him in a heartbeat!

Kevin was amazing!
Kevin was amazing! He wasn’t pushy and made looking and buying a car fun again. #1 salesmen in my books. Bridgeland and Candy Cars had a variety of Wranglers that were quality cars. Kevin also had the Jeeps I wanted to test drive waiting right up front for me! Once I bought my Wrangler, it was serviced, inspected and cleaned waiting for me upfront. I’d do business with them again.
