Thanks everyone for the concern, well wishes, and offers for advice etc.....
Here are some scary things which could have made this situation a lot worse. I have a BMW e30 M3 race car that was parked next to the 911. I had emptied a 5 gallon jug of race fuel into it the weekend before and had forgot to put the gas cap back on. I had another full 5 gallon jug behind the M3 and also a 5 gallon container for the lawnmower.
The fire appears to have started near the three fuses in the engine compartment back left. Unfortunately the fuel accumulator was keeping the fire going after the fuel line melted through.
I was really lucky the garage doors failed open and have a water hose right next to the doors (it is a wind up type in the brown box).
