What we're driving: The $110,000 Jeep Grand Wagoneer

Carmakers keep testing the limit of what people will pay for an automobile packed with luxury, high-tech features. Consider the $110,000 Jeep Grand Wagoneer I drove recently.

This is the largest, fanciest Jeep ever, with a spectacular interior bathed in dark walnut and supple leather that's outfitted with every tech gizmo you could want.

• It's hard to imagine off-roading in this luxury yacht — though it has a 10-inch ground clearance and can ford two feet of water.
• But that's not the point: this SUV is about exploring the reaches of American opulence.

The big picture: The Stellantis-owned brand known for its iconic and rugged Jeep Wrangler has already mined the low end of the SUV market with the Cherokee, Compass and Renegade. So now it's pushing the other end of the spectrum, taking on premium full-size SUVs like the Cadillac Escalade and Lincoln Navigator.

Details: The stately, upright Grand Wagoneer is massive and hard to maneuver — though the 360-degree, bird's-eye camera helps — yet it's still surprisingly refined and comfortable on the highway.

• It's powered by a 6.4-liter V-8 engine which gets an EPA-rated 13/18 mpg city/highway.
• It comes in five trim levels, ranging from about $90,000 to $110,000. (A slightly less grand model — the similarly sized Jeep Wagoneer — starts around $69,000.)

There are screens everywhere — including a 10-inch front passenger screen that has a special privacy filter to prevent distraction for the driver.

• Second-row passengers have a 10-inch touchscreen between the captain's chairs, and individual screens mounted on the seatbacks in front of them.

Are we there yet? The Grand Wagoneer and Wagoneer are the first in the industry to come with Amazon Fire TV for Auto, which lets passengers stream content from Amazon Prime, Netflix, Hulu and YouTube, among others.

• When you sync the system to an existing Amazon account, you can even pause programming in your home and resume watching in the car.
• A fun feature lets kids track the trip's progress, and the time to destination, just as airline passengers can.
• There's also a rear-seat monitoring system that lets drivers see passengers seated behind them on a video feed.

There are some surprises too, like an optional cooler in the front center console or a touchpad-controlled safe to stow valuables under the split front armrest.

The bottom line: You have to wonder if it's worth spending $110,000 on a Jeep, but if you've got the money, the Grand Wagoneer won't leave you asking for anything more.
