The Preferred Equipment Group 4SG defines this build. Super Cruise hands-off cruise control with automatic lane change is paired with the Advanced Technology Package — giving the driver hands-free capability on compatible highways along with the full suite of driver-assistance features.

The 15-inch diagonal multi-color head-up display keeps speed and navigation in the driver's sightline. Underneath, Magnetic Ride Control suspension and the Premium Capability Package with Active Response 4WD adapt the chassis in real time — on a smooth highway or a rough trail.

The front high-approach angle fascia and red horizontal-mounted recovery hooks signal that this Yukon XL is built to go farther than the parking lot. Hill descent control and a heavy-duty air filter round out the off-road hardware.

Inside, the AT4 Ultimate doesn't trade comfort for capability. Driver and front-passenger seats are perforated, heated, ventilated, and equipped with power massage — both with 2-way power upper shoulder adjustment and 4-way power lumbar.

Power-release second-row bucket seats and power-retractable assist steps make moving through all three rows easier. The dual-pane panoramic power sunroof opens the cabin; the Bose 18-speaker surround system with Centerpoint fills it.

An 8-inch diagonal rear touchscreen handles climate for the back rows, and the autosense hands-free power liftgate means your hands can stay full. The 16.8-inch diagonal GMC Infotainment System supports wireless Apple CarPlay and Android Auto.

The Floor Liner Package adds all-weather floor liners for all three rows and an all-weather cargo mat — ready for whatever comes in on boots or gear bags.

This Yukon XL sits on 20 x 9-inch machined and painted Talos Bronze Metallic wheels wearing 275/60R20 all-terrain tires, with a front skid plate, bright door sill plates, body-color door handles, a black roof-mounted luggage rack with side rails, sport pedal covers, and wheel locks already included. A dual exhaust system and 3.23 rear axle ratio complete the powertrain picture.

Napleton Chevrolet Buick GMC is on Kellom Rd. in Beaver Dam — about 35 minutes from Fond du Lac and within easy reach of Columbus and Watertown. We've been a family-owned group for more than 80 years, and our process is low-pressure.

If you've been looking for an AT4 Ultimate with this exact color combination and equipment, this is worth a closer look in person.
