GMC Sierra 1500 2015 Reviews

I?m going to purchase a new truck in the future.

Say no more ! It?s an excellent truck. Used it for 3 years and 7 month. No repairs needed. Haven?t replaced the break bads. Very comfy and well equipped.

Love it

I totally love my truck. Looks awesome on the inside as well as the outside. Descent gas mileage for a truck. Love the crew cab because I have plenty of room for car seats. Very fun to drive as well.
