Interesting...my 2000 OBW had the exact same thing happen. My wife and I were shoveling more than two feet of snow (!!!) from the front of the driveway and pulled the car out to shovel the other half. When we moved the car, I noticed green drops in the snow. Nothing major, only a few drops, maybe an ounce or two at the most, but a concern of course. Because of the snow, it was hard to tell how much coolant leaked. Well, needing an oil change, and my wiper motor checked out, I brought it in today. I'll let you know what they say about the coolant issue.
