With a 469hp twin turbo V8 Kompressor engine this vehicle has prodigious power. The dual side exhaust sounds incredible. This beast will do zero to sixty in a little under 5.5 seconds which makes it the ultimate sleeper until they hear the substantial roar of the exhaust rattle their ear drums. However when the windows are up you can barely hear it. This is a tight vehicle to say the least. Mercedes teased us all by putting the V8 Kompressor in the last model year for the G - (or is it? - I have heard rumors of possibly continuing the G series under a different manufacturer)
The engine and everything to do with it. The seats are also very comfortable and the view is excellent for drivers of all sizes. A short person will have no problem driving this vehicle and maintaining good seat position with a clear field of view. My wife loves it which says it all.
The doors are so heavy you have to be fairly strong to close them - not good for a child. You would almost certainly have to close the door for children less than 10 years of age. A DVD player as an option would be nice for the kids. I like the jump seat idea. Aftermarket items are slim to none.
