The consultant didn’t rush me, was patient the whole time. Also, bonus points: the restroom doesn’t smell like bleach, which is rare.
I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

My husband’s Acadia broke down, so we stopped by just to look. But the staff explained things so clearly that we ended up leasing a new one. Manager Thomas was super friendly and patient—didn’t pressure us, even with a baby in the back seat.
