I would probably tell it to hibernate after 5 minutes or something and turn off after 1 hour.
You could use a laptop battery and auto hibernate or shutdown software. Or just use the hibernation mode every time you get out of the car, and use the laptop battery to keep that going at all times. Then boot would be really quick!
Personally, I wouldn't deal with the turbo timer unless you already have one. Just use a relay and aux. from your alarm.
