Ouch, that hurts dude !! Looking at this, i dont think much damage is there to any internals.. only bumper, grille and right headlamp is affected, even fogs look intact. Price of one headlamp is around 2.2k, and denting works + painting on the bumper may cost you another 2k outside. you can use this oppurtunity to get the grilles meshed this time if you have lost your old ones calculate how much you ll lose in No claim bonus + discount in insurance.. and then think of claiming or not. If you have shown this to TASS, you d have definitely got an estimate of atleast 10k , they ll try to extract max from insurance !!
