I also am very sorry to see this and thank god nobody was injured... hopefully you have enough agreed value to cover all the money you had into her Incld all your labor..
Collect your money and move on as fire damaged cars are the worse to get involved in..
I had a couple customers leave the key on which in turn fries the dash wires along with o/heating or blowing out the coil. I always mention here when i read about someone leaving the key on and the points were closed to also pull back the dash and ck the wiring...
It's definitely. A learning experience for many here so thanks for posting this... you may have saved someone's life, house or car....
Here is the link to a thread from when the key was left on, if others missed it
