Coincidentally I drove my '09 for the last time until spring on December 1 too. We must have had the same weather here on the other side of Lake Michigan as you did. It was sunny and in the 50's. It's going to be a long wait until the weather improves!
I drove the convertible for the last time shortly before Thanksgiving. It was too cold to put the top down, and the heater doesn't work, so I don't miss driving it during the cold weather months.
Here it is 2 days later, and it is 30° with snow flurries in the air, so I guess I got the cars hibernated just in time.
But on those occasional nice sunny warmer winter days it is going to be rough not being able to drive the new Challenger! I suspended my insurance except for comprehensive for winter, so I may have to hide the keys away somewhere to avoid temptation and get myself in trouble!
