First, thanks JR! This has been one of my favorite sites for quite some time. Now with a G section I can "one stop shop" for Mercedes info.

Chris,
The 300GD IS 240D slow. Remember the G wieghs 5000 lbs, and is shaped like a brick. Top speeds hover around 75 mph.

I would not expect more maint than any other you have owned. The G is very overbuilt components are designed to last a long time. Like any used vehicle, get it inspected and try to be present for the inspection.

I like the 280GE autos or possibly a 230GE manual in SWB. I think Norm Keiser has a good inventory of used Gs. His prices are fair. That is where I bought my '95 from. Good luck and post if you have any other questions.
Brent
