PH Stereotype #2365: Crappy number plate = crappy driver.
When they showed the footage of the aftermath of that on London Tonight last night, and saw it was a black Porsche with a noisy exhaust, I was half expecting it to be wearing a TUABO plate
Just saw GA55 U on what looked to be a 420d or something of that description, didn't get a good look but definitely wasn't an M4. Spotted outside Groomsport.
