Sorry to hear of all your problems MrPB. I assume you have an early car?
Just to reassure anyone reading the post who may be put off from buying a new M3W or any other Morgan.
My 2015 M3W has now done 10500 miles without any serious
problems. Always starts ok and gets me to where I want to get to. Has driven through torrential rain several times without a splutter.
Only 2 warranty claims. A new oil cap and cooling fan that had got a bit of an annoying rattle.
That's probably better than your average 'normal' family saloon?
I carry a shed load of spares and tools in case I get stranded but have never had to use them.
Don't blame you for giving up but just wanted to add my story for balance.
