Car Exploded

This morning around 8:40, our family vehicle exploded. Our only vehicle for transportation. No one was injured. When I was close to work on the freeway I smelled burning, and as I arrived at work this morning there was what I thought was steam coming out of the engine. I naturally assumed that the oil was low, so I went inside and clocked in for the day to let the car cool down. 15 minutes later, I came out to check the oil with a co-worker. The entire parking garage was filled with thick black smoke, and as soon as we started to turn around the corner, the car exploded. All I saw was orange and smoke. We went back inside and I yelled for someone to call the police. The fireman said that there was no  foul play. Right now I'm a bit of a mess from shock. I'm thankful my co-worker and I hadn't gone out any sooner, as we almost did, but now my family is left with no transportation. We have been waiting for my tax return so that we can get a second car, but after filing in March, we still have not received a dime. Please help us help our family. Anything would be extremely appreciated. Thank you for your time.
