Im thinking about selling my truck and don't know exactly what it's worth or what other people think it might be worth because of the add on's that I have etc. I have a 2009 silverado extended cab LT 2wd with the 5.3L flex fuel motor. It has 85,xxx miles with a 2" rough country leveling kit, 295/70/17 Toyo MT's with 40,000 miles (ab 25% left), 4:10 gears in the rear, an airaid cold air intake, single in dual out magnaflow exhaust with 4" tips, 2 12" kicker cvt's under the seat with hifonics 1000W amp and 4 replacement hifonics 6.5" door speakers and 4 1" tweeters with amp, marathon seat covers, tint, and a custom tune. NADA and Kelley Blue Books put it at 16,000-17,000.
