G55 is a bit over the top but sure it is nice and
one of the true real off road vehicles not a poser SAV's like BMW X5 and alikes.
The G500 is what you can feel as "enough" the G55 is something of an adrenalin shot to a racer. A little overkill but hey if you can afford to keep it and pump gas in it, makes perfect sense. BUT and this is a serious consideration - the new GL450 and probably soon GL500 and GL55 or GL63 is a whole lot more truck. Still capable off roader and an all around better performer. So unless you want to do serious off roading in the G55 then GL class is lightyers ahead of the G series. Still MB and still 3 diff and still everything you ever need but a little more in a more sophisticated package.
Larger cabin, more refined interior and better handling. (oh, handling is actually a handling not crwaling over like in the G)
don't forget the basic design of the G originates in the early 70's with military in their mind. Sure it can be entertraining off the road but how mnay times will you actually get into the mud/slush and harsh terrain in a 65+k usd vehicle ? if you do I suggest you buy 2 vehicle, a GL450 and a Jeep Wrangler Rubicon and enjoy the little thing on a weekend and have fun in the GL during the week.
By the way I like the fact that you kept you 840 even though you have the Z8 ! Most people who had 8 and then went for the Z8 dropped the 8 out of their fleet !
