Hi dx100uk,
Sorry, link to what?
About knowing who the registered keeper of a car is from DVLA, correct, they can, if with a valid reason, and as long they're members of BPA or IPC, as far as I can gather. Parkshiled, in the case, is a member of IPC.
Digging further, this Parkshield has amazing stories. They do look like a business made of extorsion. Now I may have been naughty and parked for 20min where I shouldn't, but this is becoming something more than £100. The more I read the more it's about the principle.
cheers all
