Send them a letter acknowledging that they have took the vehicle and then invoice them for the same amount as they want from you. Then to take the piss even further go to the small claims court and register your claim against them and feck them with a judgement ......

It probably wont work, but it'll be worth a go just to have judgement against them









Or just got out and get lashed ...On the plus side you wont get nicked for drink driving
