Black 205 pulled out in front of me as I was coming out of Eighton Banks heading for A1 (Bowes Incline). Standard looking apart from black quarter windows, exhaust and a private plate (which I can't remember :

)
Managed to get along side but didn't recgnise the driver and didn't beep because I was in my other 4. Ahem, Volvo 440 that is...doh
