This has come up many times every since Mercedes announced they were putting the old guy out to pasture.
I too will miss the "G", but I think Mercedes has to keep up with Land Rover and Lexus in the high-end luxury SUV game and the current G just ain't it.
Now, I too don't like the fact that this new ML-based GL (as they are now calling it) won't be what the current G is, but thats the price Mercedes has to pay since they've become about volume now.
Back in the old days Mercedes would have re-designed the G with its own platform and priced it how they pleased. This is personally what I wanted. A new G with the look of the old one (you know like how L-Rover keeps the Range Rover shape from gen to generation), built in Germany with the same quality of the new S-Class and the ability of the old truck off road, with the luxury of the S-Class and priced anywhere from 80-90K for the G500 version.
Now enter the world of shareholders and profits that must be made immediately and enter the shared platform with the M/R-Classes.
I don't like it either, but it is what it is. Plus the thing looks so damn common. Oh well I don't like SUVs anyway!
