Welcome to the Clan Nigel; Sorry been away for a few days so only now catching up on things.
You have basically bought a 4/4 at a hefty saving, despite what it says on on the car. The lack of Louvres is not going to cause you any problems in terms of over - heating with a Ford engine. As you mention, Louvres are an 'Option' on the current 4/4; like everything else - a 23k Base Car can easily cost that amount again in extras !
Morgans are individual cars and like dogs, they/you eventualy become one! Congratulations on your choice, in IMHO, the 4/4 remains the Morgan most in - keeping with it's heritage and more importantly 'in cinque' with it's chassis and suspension design - ask Speedmog!
