Marilyn has awesome product knowledge found exactly what
Marilyn has awesome product knowledge found exactly what I was looking for. My experience was a smooth no pressure transaction.
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.

I made a last minute appointment and was accommodated in a timely fashion. The service was excellent. I wax just in there for an oil change and a tire rotation and it was cheaper at the dealer then on the outside.

Got my Sierra here.
Got my Sierra here. Quiet, no pushy talk, no showroom theatrics. Just walked through the details, got offered coffee, and signed. I liked that they let the car speak for itself.
