I wasn’t at home the day it turned up so was only aware of its arrival thanks to a text from my teenage daughter which read, ‘GWAGON! GWAGON! GWAGON!’ followed by a series of photographs of her grinning like a loon from inside, outside and roundabout the car. And the point is this: said daughter is really not that interested in cars in general and large SUVs in particular. But G-Wagons are different.
