I have to leave my M3W at my house in France for a few days, while I go back to the UK for my granddaughter's christening and it would be quite easy for people to come in and steal the Morgan, as folks quite often wander into the grounds to look at the view, which is rather special. I would guess the steering lock would last a few seconds with a heavy screwdriver and spanner. I do have a battery isolator switch but a quick look under the bonnet would spot that one. Is there a relay I could remove, say for the injection system. I normally put a heavy chain through the wheel and round the front wishbone but I am using that for my quad bike this time.
