Buying my Telsa from Performance Nissan was fantastic, thanks to Naej Charles. He patiently explained all the car's performance capabilities and showcased its unique features, ensuring I made the right choice.
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.

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.
