Also, what is so great about the GL? Pretty sure in 10 years when we look back at cars from this era, we won't swoon over the GL (nor would we for the 7 series), but I think it's being made out to be a much better car than it actually is.
A used 7 is going to need maintenance. If you've ever serviced a BMW out of warranty you know it's not cheap. The used 7 will also continue to depreciate, just to get the math straight. Next, it was a 450 I was telling him, not the 550. It will be in warranty so no worries there. Also, I would lease vs. buy as MB is putting out some heavily subsidized residuals and a ton of dealer dollars to knock MSRP down. He also mentioned he was considering an SUV...and last I checked, the GL is indeed an SUV.
Given all that there is no comparison between the two vehicles in a head to head. Completely apples to oranges. However, if you want a luxury SUV, I think the GL is a fine choice. I know I've been happy with both of mine but obviously YMMV.
