This should be good to watch. Not often the Alvis 6x6s get an airing, but whenever they do it's always the Saracen and the Saladin. Their soft skinned cousins always get forgotten. Nothing, but nothing raises the adrenalin more than an 80 mph cross country run in a Stalwart ... especially when it flies straight off a river bank and keeps going across the water.
Don't forget to shut the top hatches first though.
I gather that the Salamander wasn't much slower when it's water tank was empty.
