2008 Mercedes-Benz GL320 CDI Review

Competition

My no-options GL320 CDI costs $71,500, while the GL450 sells for $82,500 and the full-tilt GL550 goes for $91,000. Mercedes-Benz clearly stated the GL's direct rivals: the Cadillac Escalade and Lincoln Navigator. There are a couple more full-size luxo-SUVs on the market, too. Anyway, here's the pricing breakdown:

Cadillac Escalade, $76,960
Hummer H2 SUV, $72,295
Range Rover, $100,900
Lexus LX 570, $84,600
Lincoln Navigator, $73,299

None of them offer a diesel engine, but the Escalade will soon be available with a hybrid powertrain.

Real wood and silver trim brighten up the otherwise dark environment.

Conclusion

The GL320 CDI has all the virtues of its more-expensive brethren, but with an engine that delivers better fuel economy, although the difference isn't really enormous. I have the feeling that if there was a gas-powered base model alternative, not many people would choose the diesel. Why?


Diesel-powered vehicles are no longer smelly and dirty, but diesel fuel pumps at gas stations still are. Every time I fill up at a diesel pump, there usually are puddles from people trying to top off their tank and overflowing it. The pump itself is covered with a quarter-inch of oily grime, and I leave the station smelling like an old furnace. For me, a diesel car or truck is a turn-off just for that. I could always stop at a full-service station, though.

Diesel or not, the GL-Class is a competent big SUV that glides its numerous occupants down the road in luxury and smoothness. If you like driving a vehicle that feels built from a solid billet of steel, you'll probably like the GL320 CDI.
