nice car and nice dealer I like it too much. Thanks for your help and advice
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.

What a great experience buying a truck.
What a great experience buying a truck. I'm from Pittsburgh, Pa. I saw a truck that i liked on line at Motion autosport dealership.The salesman was named Mike. He was very professional and was very knowledgeable. He always called back with any question i asked. I feel that I got a great deal and the truck was show room condition. There was no xxxxxxxx games.The finance manager Jenn was super also. She was straight to the point. Thanks Jenn. If your looking for a great deal without all the games dealerships play go see Mike at Motion autosport in North Canton, Ohio. Thank you Mike for a great experience. Mike M
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.
