I have a G and the body/frame is on par with a G. What do you think they did for that 1500lb weight difference between A 4 runner, and a Grenadier? stick a massive chunk of iron under the passenger seat?
The reason you buy a used Gwagon, is first of all, for the luxury trim, the exact opposite of simplicity. Then maybe the drivetrain. Then maybe the dealer network. And lets not forget badge conscious fanboy ********. Brand new its 2x the price and people will think you have more money than you have. On the flipside, one has to then keep in mind the sticker shock of Merc "out of warranty repairs". It's pure joy.
If a person actually WANTED a non luxury, new Gwagon, reminiscent of the Europa unit 463's, that had C class interiors and not S class trim like the later 463's, This is it.
But telling me you opened the doors, drove the Gren, then got out, and your impression was 4runner is friggin' funny.
