Ah! So now we know the secret: no louvres and no door handles = improved aerodynamics
The standard model has the aerodynamics of a brick, Stanley has the aerodynamics of a brick with round corners.
In the age of being PC we need be fair to Stanley - he is 'louvrally challenged'!
I have just spent a few minutes trying to word a suitable witty riposte, but to no avail.
I will therefore retreat to the garage to grease Stanley's springs, in readiness for TOTH.
Note to Mods - can we have a smiley that is blowing a raspberry, one I could use for an educated reply to such comments!
