Couple of months is not really a long time. I agree with stretch, the product is called damp rid? Disconnect the battery when parked. It will be fine when you get back. Definitely fill up the tank and add whatever fuel stabilization liquid your car needs.

My parents store their 93 300e this way in Greece for a year or more.
