When you're driving something that costs as much as a mobile home, it's hard not to feel like King of the Road.

That's the impression conveyed by the Mercedes GL 450 SUV, an all-wheel-drive vehicle with a base price of $55,500. It could be the world's finest.

Driving the GL 450 is pure pleasure. Outside, it's elegant, especially with the optional-for-$700 Verde Brook paint. Inside, it's all business, the analog/digital wood-trimmed dash containing a plethora of gauges.

Its twin front buckets are leather ($1,650) and designed to cradle even the largest driver. Behind the folding second and third benches - the hindmost is for kids - is a small trunk. The front buckets are power operated and heated with cup holders secreted in the center console.

The vehicle utilizes a "start" button and electronic key called "Keyless Go." And for $1,100, you should let it go! Along with a smooth-shifting seven-speed automatic transmission, it's state of the art. Both driver and passenger airbags protect the occupants, along with electronic stability and traction programs, Brake Assist, Electronic Brake Force Distribution, four-wheel disc antilock brakes and Tele-Aide, the Mercedes version of General Motors' Onstar. Options included Voice Control over many functions ($500), a Back-Up Camera ($500) and a $900 xenon beam headlight package with a few other gadgets.

Other features include an anti-theft system, load leveling height-adjustable suspension, an MP3/iPod jack, power locks and steering, cruise, tilt steering and much

As you'd expect in such an expensive beast, the all-wheel-drive powertrain is superb. Its 4.7-liter, 335-HP V8 is velvet-smooth and quiet. Zero to 60 times were observed at 6.9 seconds - best in class. Fuel economy was recorded at 13 city and 16 highway (EPA 15/29). As this 5,249-pound vehicle employs all-wheel drive, it's equipped with Hill Start Assist and a Downhill Speed Regulator. An Off Road Package with numerous features is $2,200. Despite such items, there's no Hi/Lo transfer case. The GL 450's built for inclement weather, not off-roading.

Ride and handling were better than expected. That means a firm four-wheel independent suspension. It's adjustable and varies ride quality between harshness and comfort. The tires are excellent, all-season radials.

The automatic heater and air conditioner excelled. Quality control was flawless, and the sound system was well above average.

Criticisms? The brake pedal is spongy.

Driving a GL 450 is an experience - and it's bargain-priced.
