vehicle storage

[machucam]

I have a '99 WS6 and will need to store it for about 6 months. It will be left in a garage. I may be able to have someone come and start it say once a month. Is there anything special I should do? Should I lift it off the ground on jack stands?

Thanks,
Michael

Leave the car on the ground and increase the tire pressure to 45 psi so it won't have flat spots
