Can someone shed some light with this chassis?

I like the Pajero as it looks real, I'm not into rock crawling however I was wondering how this car would go as a fast offroader?

And even on road? I don't expect it to handle like a touring car, but can it still be fun to drive fast?
I understand it has a 3 speed manual gearbox too?
Can gears be shifted while moving? If so, can they be downshifted while moving?

Can it go through some water?

The other one I was looking at was the F-350 High Lift, but I think it's quite expensive + it just does't look as good

Thanks guys

PS. What other brands/cars are there similar to the XC Pajero?
