from what i know and i dont know much..... basically have a check over everything and see that its all in good working order.
main things i would think would be fluids. Oil, Coolant, PS fluid, Brake fluid. See if theyre good or in need of a change or top up. also you should really bleed your brakes.
thats all i can think of, anyone else feel free to add or correct stuff that i have said.
