I played a game of tag with the pictured vehicle a few weeks ago. I spotted it during evening rush hour on the M25, and kept sight of it along the M26 and the M20.
I have no idea what it is - the rear side windows may give a clue to someone, as well as the blank space for the large oval badge on the grille (Kia/Toyota?).
Although the model pictured was a five-seater, it did look to have sufficient space for a third row of seats. It is a south-eastern England registration plate, and it's right hand drive too.
The passenger was none too keen to be photographed! Despite the at-first rough appearance, it was quite a complete and capable vehicle. Anybody got a clue what this is?
