C**t's Who drive off after hitting your Car

Right i am throughrally pissed off now. Right on November the 6th a complete asshole in a Dark vauxhall Cavelier 1.8i registration L398 WLU reversed into my mini smashing the light..... i didn't persue him through the police as it is only a £30 light (his details were kindly written down by a neighbour). Now today i go out to my car and find that somebody has smashed into my mini again taking the rear wheelarch off..... there was a note left by a neighbour saying they thought it was a focus.... unfortunately they were unsure about the numberplate.... however they are sure its a brand new 54 plate car so its not like they couldn't afford to stop and pay for the damage caused...... I'm just about to go find out how much this is going to cost me this time :cry: I'm not even gonna be able to park in my own street anymore and that is sad really... i'm going to find a safer place
