There have been no symptoms...I mean it's been super cold here in CT...so it has a slight hesitation on startup...but that would happen to any car at 2-3 degrees + windchill.
The reason for my question is primarily related to the fact I'm about to leave her in JFK long term parking for 8 days next week.
