Dealer notes
The 2026 GMC Sierra 1500 SLT Crew Cab at Napleton Buick GMC in Crystal Lake arrives new — delivery miles only — in Onyx Black over a Jet Black perforated leather-appointed interior, and it stacks nine factory packages to deliver a truck that is equally at home on a muddy two-track and a long highway run. Twenty-inch polished aluminum wheels wrapped in 275/60R20 all-terrain tires, an X31 off-road suspension, skid plates, and hill descent control give it the hardware to back up the look, while ventilated and heated front seats, a power sunroof, and a Bose 7-speaker system mean the interior earns its keep every day.
