After a couple of weeks I was experiencing increasing lower back pain, but it took a while to identify the cause, being the angle of the seat.
The problem is, due to my height, if I set the seat more upright, I am pushing my head into the roof! and the seat cannot be set any lower.

Agents could not offer any help either.
So, after a very brief "fling" with the Pajero brand, I am defecting.
I have bought a new Defender Puma.

Wishing you all well.
