Heavy-duty personified, the new GMC Sierra 3500HD, offered in Oklahoma City, is ‘real steel’ when you have to get tough jobs done. Whether it is projector-beam headlamps with HID bulbs, LED signature front lighting or Available Amber Roof Marker Lamps, everything projects its image of powerful truck. The new GMC Sierra 3500HD, Oklahoma City drivers, enables you to control heavy roads with a host of features like Stabilitrak with Hill Start Assist, Trailer Sway Control and Traction Control, front and rear park assist, and more. Despite all this, it has a very quiet cabin, owing to triple door seals that block outside noise. Bob Howard Buick GMC presents an extensive inventory of new vehicles on its lot. We look forward to seeing you soon!
