i'd follow them, if that wouldnt b enough to sh*t them up id probably do something with their tyres when they leave the bmw...something my dad told me to do when i get abuse riding my ped or people try to knock me off for no reason like they do ..
follow them and see where they live then go back and attack their tyres
luckily sean it wasnt something hard and didnt ruin anything
My cars well dirty now tho, The wheels dont look new they look years old and i just got mud and dirty water all over my baby , Hope weather is ok 2moz so i can spend the day cleaning her
