I have thought about this in the past and not Gone any further due to the costs that I assumed would be involved, And knowing that a lot of damage would be caused to the cars etc, Then I would end up spending more time repairing my own cars rather than customers. If This was a Chargeable Service and the costs could be covered easily, then it would be worthwhile. ?? How much is the Insurance for Loan or hire cars, ?? A lot of Car/van hire places around here Closed down due to escalating costs of insurance etc. ??
