The spoiler, the lip spoiler, the alloys & tyres, the lower mesh grille and a Pioneer Satnav were all fitted as extras via the Dealer before I picked it up so the insurance are happy and they are all classed as 'factory fit'. Those externals set it off for me :D
Nope on the reg number... I bought the plate for £269 on 16/09/13 via Plates4less, which included the £80 DVLA fee and it was registered as a 1st registration with the Certificate of Entitlement that I forwarded onto the Dealer, so that they could register it on 30/09/13. Very easy, it never had a '63 plate allocated.
