hit up the insurance, in the end you will get fucked over otherwise
as for light damage
wifes friend was bumped and saw no damage so didnt worry
i looked and while her laguna bumper looked ok her boot floor was up and split and wiring trapped and damaged blowing fuses and no lights
dippy cow didnt even get a reg
hope you took pics, they could try the reversed into ME thing and you get fucked
i have a claim pending and guy who hit us said it was not his fault pic cleared that one up with no hassles
(i put a pic on my thread)
