I used to just start the car up check for leaks etc and also check all the fluid levels.
Before I came to drive it I gave it a coolant flush as the cold weather gave it a jelly like substance, I also did an oil,fuel,and air filter change just to make sure it was ship - shape when i took it out on the roads. Also it helps if you move backwards and forwards to stop the brakes sticking.
hope this helps!
