It seems like just yesterday the Mercedes GL-Class was unveiled to the world, but actually, it's been nearly three years since the seven-passenger SUV made its official debut.  As those of you familiar with Mercedes know, the three year production mark traditionally heralds a mid-life revision, and it appears the GL-Class is no exception to the rule.  Spy photographers captured shots of the SUV recently bearing an assortment of light camouflage, a sure indicator that a slight re-engineering is on the horizon.

After looking at the photos, here's some of the areas the GL will have nipped and tucked. Firstly (and obviously), the front fog lights will note a revision, possibly with LED technology. The lower band of the headlights could see a revision as well, à la the new generation M-Class.  Despite the lack of masking, new side mirrors are another notable change.  And in the back, a modified rear bumper, a reshaped exhaust and slightly revised taillights are all present as well.

Aside from these changes, we weren't able to discern any other differences, although a few interior tweaks should be present in the luxury sport-ute. We will of course keep you posted as new details emerge, but in the meantime, keep scrolling to see a few additional spy photos of the 2010 Mercedes GL-Class, then head over to GlobalMotors.net for the full 2010 GL spy photo collection.

Enjoy ladies and gentlemen.

And before we go, a special thanks to Andrus, the industrious reader gracious enough to send us the tip.
