Not a lot of people realise it, but Nos is right. Unbraked, you can only legally tow 50% of the weight of the car.
Talken from the link he posted:-
"Type 01: unbraked trailers - max. 750kg gross trailer weight or half the towing vehicle's kerb weight - whichever is less. "
So for a 750kg rig, you have to have a pretty big car, like a vauxhall Omega or ford scorpion in the large saloon market or a 4x4. Freelanders for example come in at about 1500kg.
