Short version is you now have heat. :D
Anything is better than being cold.
I decided I'm going to get one of those little electric/ceramic room heaters and mount it up under the dash blowing down.
Then I'll wire it out to the front bumper and put a socket for the electric cord up under the bumper out of sight.
Then on real cold mornings I can plug it in and go back in the house.
The other day all the windows were frozen, and the doors were darn near frozen closed so I took one out and set it on the floor.
10 min later all the windows were defrosted and it was probably 80 or so inside the car.
That made starting the car and warming it up WAY more tolerable when it was freezing A cold out. :D
I park right by an outlet on the house anyway, and I frequently have to take off for stuff in the mornings.
You northern guys might consider something like this if you drive your classic year round like I do.
