Hmmm. Initial reaction is “wrong on many, if not all, levels”. Rolls Royces should not be great lairy, flashy, footballers’ tractors. Leave that to Bentley (and even that’s wrong). But, there again, Rolls does have a history of tough, off-road and, dare I say it, fighting vehicles. Look at the RR desert cars used in Arabia during WW1.
Now, if they offered one of the new design with a gun turret, that could be well useful on the M25!
