Booked car hire in the UK - London Gatwick. The company wanted a deposit of $3,000 as security, providing a credit card was insufficient. Also, it would take approx 28 days after the hire for it to be reimbursed. To side step this they offered full insurance etc for around $600 Aus - that was just under what we paid for the car. Luckily we had the cash for the deposit but there were many other very unhappy customers. Additionally, don't be fooled by a VW Polo or equivalent, the equivalent is sub standard. Never again. Customer service was good as they use other hire companies.
