Just lend it to me for the winter and I'll park my 20 year old Rover in your garage!
Seriously, if you are going to park it up, use a maintenance charger similar to:-

If you can, jack it up on axle stands or move it around to rotate the wheels occasionally. Run up to full operating temperature at least once a month and use all the electric ancillaries to keep them moving (+ washers, wipers, mirrors, locks, windows,doors, clutch etc.). If it's a petrol, you can add special fuel that won't go "off"!
I envy your motor, being kept snug for the winter!
