As we spend most of the winter at our place in Spain, I aways SORN our Morgans, from Nov through to April.
I found such a massive improvement with my Arthritus spending the winters here that it became a no brainer.
My concern is always starting up the car after a long layup but I've found removing the fuel pump fuse and spinning the engine a few times to circulate the oil does the trick.
