put the car up on blocks for starters. add fuel stabilizer made specifically for storing car. (can't remember the correct name) I had a Schumacher battery maintainer. did an awesome job. it keeps the battery topped off with a trickle-charge and only comes on when the voltage drops. (can't remember the level, it's somewhere between 11.5 and 12) the oil should be changed as paraffin based oils will break down and become acidic after three months. if you use synthetics, you should be o.k. there is also an oil replacement product made for storing cars, the name of which of course, you guessed it, I forgot
