Short term basicly just take it on a decent drive once a month to stop it all seizing up. I've no electric in the garage so I've bought a big solar panel and sticking that to my garage roof this evening and running the wires in so I can keep it on a trickle charge. Pain having to keep using a jump pack and it kills the battery on the car, currently go through one every 6 months! Long term it needs quite a bit of work including a full respray but I'm going to wait u till we get a house with a decent sized garage so I can strip it back to a bare shell and start from scratch. Just for now I'll keep using it every now and again
