Tow hitch mounted are by far the best bet- however I am not sure that a supermini such as the A2 would have provision for one?
Also being aluminium welding would not be easy.
Edit: found some info.
Audi do have a tow hitch kit, you will have to cut the bumper and drill the underside of the car then rivet in place though. Also be aware of electrolytic corrosion between steel and alloy parts.
part numbers are Towbar 8Z0092155 £260, Electrics ZGB8Z0055203 £70
