Ok TWO spotted today (Friday) when I was travelling from Portsmouth to Billingshurst late afternoon.
An unbadged Mineral Grey with what looked like ED alloys - it followed me along the A27 between Chichester and Fontwell where I headed northeast up the A29 and it continued along the A27 towards Arundel.
Second was a AW Sport spotted in Pulborough at the two mini roundabouts. Only caught the front view unfortunately.
