im pretty certain they cant take a disabled persons vehicle where the vehicle is his only means of getting round.
also they cant take anything needed to do your job so if the cars vital for work thats another reason.
also whatever you do, do
NOT pay a penny to the baliff. pay it to the council direct. Same with court fines. the charges are only legally enforcable if you pay through the baliff.
when the baliff gets bored and returns the account to the council for further enforcement, all the baliff charges come off.
I did that with a court fine i disputed and refused to pay. Baliff cunts tried to up the fine from £140 to £380

. Funnily enough i never heard from the baliff once i had settled the matter direct with the court.
