Looking beyond it's "luxury extra's" I wonder of there's a bit of history behind the motor.
I can't see an individual going to the lengths they have to modify the base vehicle. I wonder if it was built for a special purpose, de-commissioned and ended up like this.
Perhaps someone knows something we don't and thats why there seems to interest in it.
Or alternatively, maybe a large sofa retailer is trying to buy back its stock!
