Sad to hear about the damage Pran! a very similar incident happened with me a month back where my punto touched an auto from behind. it was just a touch without any damages. my front bumper was already damaged with a dog hit so i didnt even care to stop. but in the next traffic pile up (not a signal) that autowala came next to my car and started abusing. i told him nothing happened boss.. leave it. when i didn't stop he took out his right leg and banged at the front passenger door. luckily not much traffic was there ahead of me and i was already trying to sway my car away from him.. he tried to hit two three times more but his leg could not reach my door.. after that i moved ahead fast and stopped after some distance to check if there was any damage on the door. to my relief nothing was there. about the den't on your door: if you don't mind giving it a try some dents can be taken out/reduced using the rubber mount of your gps (the thing that sticks to the glass)or any similar thing. the catch is it should stick on the dented surface, if it sticks then pull it with some force. i have tried it once on my right fender where i was able to remove about 75% of the dent.
