Thanks for all the feedback folks. "Wisco" it's almost nice to know I'm not alone with your very similar issues - input very much appreciated.
But you all have permission to hit me about the face with a wet fish...
... Upon checking the Aero again this morning, I discovered that access to coolant was easy from other bonnet opening. Doh! It seemed from off-side opening to be absolute central so had assumed (quite wrongly) that access to it was same on both sides. Assumption is the mother...
So I have now topped it up to minimum level (the level guide was within) and going to check for any leaks, which I suspect may exist.
Central locking/alarm still gone awol but that's ok as I was actually expecting it go off when I entered using key only. As most other cars would.
Once I am satisfied all fluid levels correct, will take it for a long drive and then next step will be to drop it in for a complete spanner check/service with RPM in Perth. Russell seems very enthusiastic/knowledgeable about Morgan and a pleasure to deal with when I visited him last year. Hopefully he can advise/fix door windnoise issue, otherwise a visit to Malvern will be required.
Cheers,
Alastair
P.S. Pic attached but on previous owners reg. I have new period plates made up now for reg "MOG 6G".
