Leaving the country for a month. The 525i will sit in my garage during that time. Any tips? Some have told me to leave it in neutral, no hand brake, chock the wheels, fill the gas tank, and leave a window open to keep it fresh inside. Others have told me opposite of these things. Its only a month so I would assume a full winter prep is not needed. Just got Inspection II done so I'm good on fresh fluids. Thought you guys would know the best answer. Thanks for the help guys!
