That's good to know Richard. With the Z06 I'm thinking 3 weeks would not be ok; but really do not know. I was warned not to leave the car unplugged for more than a few days. I actually do not know the difference between computers and battery draw with the Stingray vs Z06.. if there is any. I would expect there would be some though with the Mag Ride etc.
Hope somebody does and clears this one up for us.
I have never left any of the 3 Z06s unplugged for more than a few days so have never experienced the "dead" battery. However, it's good to hear one can forget for a week or 3 and not have a "Homer" moment getting back to the car to go for a ride.
