Recent Arrival! The 2025 GMC Sierra 3500HD AT4 in Onyx Black has officially rolled in, and its every bit as bold as it looks. With a mighty Duramax 6.6L V8 Turbodiesel under the hood, this truck is built to tow, haul, and take on whatever challenge you throw at it without even breaking a sweat. The AT4 trim means you're getting serious off-road capability with premium interior touches, because who says rugged cant be refined? Whether you're hitting the jobsite or heading out for a weekend escape, this truck handles it all like it was born for it. Its intimidating in the best possible way think of it as the truck version of a firm handshake and a confident nod. And let's be honest: in Onyx Black, it might just look better than you do. To sweeten the deal, it comes with the 2-Year/24k Young Auto Group Maintenance Plan, which includes free oil changes, free tire rotations, and free safety inspections for two years. That's peace of mind built right into the price tag like having a personal pit crew on speed dial. Just a heads-up, the price doesn't include any dealer-installed options or accessories, so those extra bells and whistles are up to you. New vehicle pricing may include rebates and manufacturer incentives, but keep in mind, not all buyers will qualify. As always, tax, title, and license fees are extra because the DMV doesn't take diesel power as currency. So, if you're ready to command the road with strength, style, and confidence, the 2025 Sierra 3500HD AT4 is parked here waiting for its next boss. *Disclaimer: Contact dealer for details.
