I wouldn't use either of those terms to describe it, naff isn't nearly the correct word. Hope the driver gets a ticket for bulging over the parking space.
Considering that the price of a Holland and Holland Range Rover is a minimum of £140k and the cost of a pair of their shotguns is a minimum of £200k, it is likely that the owner:
A). Is a cunt.
B). Won't give a flying fuck about a parking ticket.
Not sure if this is ace or naff, LWB Holland and Holland Rangie
