Trim: SLT Take a look at this super clean 2008 GMC Sierra 1500 SLT we just got in on trade for a Pre-Owned Toyota Camry. We did an inspection in our service department and at that time we gave it a fresh oil and filter change installed new wiper blades and replaced a couple marker bulbs. That was all it needed and we did the service so you don't have to. This Sierra is very well equipped with features like Leather Heavy Duty Trailering Package 20' Wheels Running Boards and more. Stop by for a test drive today this one won't last long.
