On the classic there is only height adjustment on the drivers seat, the lever on the side, do any of the next models up have this on the passenger seats???

Yep the 4x4 certainly does but not sure about others.

vRS does too

And Elegance does

That just leaves the ambient ????

I may as well ask, has anyone got one spare with black outers and grey inserts

Yep, my Ambiente has it too ;-)

My Ambiente +stuff has both in height and lumbar adjustment.
