Yep - the car is not important mate. You and your passengers are! Glad you seemed to get away with it!
One thing is that if the airbag goes off the impact has been considered "severe". Lots of users report more serious accidents and wonder why the airbag has not gone off. It hasn't gone off because they are clever enough not to deploy unless absolutely necessary. If it has gone off, I'm suprised there is no damage to the vehicle but I'll be happy to be proved wrong on that one!
