My 8 will be standing for 2 months!!

I recently bought my rx8 about a month ago with the idea of selling it after my summer holidays. Problem is I like my car so much and i've invested so much time and money in it i dont have the heart to sell it. The problem is I am a student and i'm flying back to England next month for university. Ill be back around Xmas time for my break. My car will be standing for almost 3 months!! Any suggestions as to what i can do as ive heard its really bad for engine to be unused for such a long period of time.

Thanks so much.
