1) Get an oil change/tune up
2) Fill you tank full of gas
3) If you are storing over 4 months, you will need fuel stabalizer.
4) Wash your car thoroughly on the inside and out.
4a) Open your windows a crack
5) Empty everything from your trunk and interior.
6) Loosen all four wheels
7) Jack up the front end of your car then put your front end on car stands. (On the contact points of course)
8) Repeat step 6 for the rear end.
9) Remove all wheels. Store stacked up with the bottom tire resting on wood slabs.
** For steps 6 and 7, you will need to ask someone where your rear and front jacking points are. (So it jacks up the WHOLE front/rear end and not just 1/4 of the car)
If I forgot something please add to this post!
