After less than 700 miles?
I would leave it and just start the car every week or two, idling until warm. This is good for the battery, too. Roll it a bit to prevent tire flat spots.
Being in Colorado, I guess your winters are longer, but here in Missouri, the snow season is maybe 3-4 months long and winterizing is a complete waste of time and money. Until/unless the roads are salted, I keep driving it all winter.
We hardly ever get snow here anymore.
