I had a tear up with a bloke in a Carrera 4S (I think it said on the back, was more worried about the blurry things at the windows than what his badge said).
Was a mad little blast and he gestured we go back along the dual carriageway. So we did, next set of lights he asked what I had under the bonnet and he seemed to approve with a big grin.
Unfortunately there is nothing stoping an idiot buying any car
