"Ok, some rule of thumb maths here.

Let's say a standard 4x4 car (I drive an X-Trail for instance) is 1.8 metres high. It's approx 4 metres long, by 3 wide. I make that a volume of some 21 and a bit CuMtrs. "


3M wide, 9ft 10 ins in old money!!! Are you sure?

Jim.

I did say rule of thumb! :-)

Ok, take 2M x 4M x 1.8, give s afigure of 14.4CuM.

That makes approx 8.5 carloads of space! Even worse. Almost half as many cars again!
