Depernds how long the car is to be stored for, it would be best to run the fuel out as petrol sours over time, remove the sparkplugs a squirt of two stroke oil down the bores, elevate the car so that the wheels are off the ground leave windows slightly open to allow air to circulate,,, obviously washed and dried before. remove the battery
Just a few things sure there are a few more, dont think it needs servicing, just a going over. I would also consider a carcoon
