Agree with the others.. I've had one read up and ignored it, got another, ignored it, got another, ignored it.... Never heard from them again. It's a total scam for people willing to give up their money when someone comes up with a convincing official sounding letter. As said they can only claim from you what they've lost and in a car park that's free or very cheap, they won't ever bring it to court even if they threaten it
