Ouch! I'm glad no one was hurt. Hopefully you can get back at least what it was worth.

Either I'm not getting it, but I think even though fire needs oxygen it would've burned up either way with the door open/closed. Cars aren't air tight so it would have turned out the same.

BTW what took the fire dept. so long to get there? 45mins is a LONG time especially if it was a house fire, lives would've been on the line. Fires only take a few minutes to engulf a house.
