This is a 2013 GMC Sierra 1500 SLT All-Terrain package with a 5.3L motor under the hood. It was bought brand new in May of 2013. It's loaded out with dark interior and is white on the exterior. It's a 4-door crew cab with everything except navigation. The screen inside the cab is an aftermarket JVC audio screen which I put in to replace the stock navigation screen. It connects to cellular Bluetooth audio for calling and also Bluetooth music for a cell phone. It also has AUX jack hookup, andora radio capability, VD player, nd standard AM/FM radio station connection. There's also a stock backseat TV on the ceiling of the cab that doesn't work. It has a sunroof, nd I also installed black WeatherTech floor mats to match the interior carpet & leather. The cab seats five people with a middle console in between the front two seats.I added quite a few exterior aftermarket accessories. The truck windows are tinted to 5% with a 10 inch windshield strip. I put a 2.5 inch Rough Country leveling kit on the truck with 33/12.50/20 inch tires. It has a spray-in bedliner with a black FWS toolbox that sits in the bed. There are black L.E.D. brake lights installed. I also put 8,000k H.I.D. bulbs in the stock fog, im, nd bright headlights. I also put dual Magnaflow exhaust pipes on the truck as well as an AirRaid cold air intake system. I also added Diablo 450 performance chip. The truck is in great condition, t has no issues, amp; runs as good as it did new. The truck has 57,700 miles on the odometer and I have been the owner since it was new in May 2013. My reason for selling is that I am a college student and need something cheaper and I want to get the remaining worth out of the truck.
