The liquidators can't hold or take posession of any of Genesis' customer's cars, or any assets not belonging to Genesis. That's bullshit. Go down there with your proof of registration, insurance, drivers license and demand your car be released - If not, then a stolen vehicle report against the liquidators at the local police station will sort them out. You have the right to recover your property, and also take legal action against them for personal loss or inconveniences caused as a result of any delay.
