Glad it’s sorted this raises an interesting question. If they transfer insurance and the car is on the public road, obviously it’s covered by Europcar insurance BUT they have no knowledge of the state of that car. On top of that if you park it there they collect days later and someone keyed it or worse crashed into it who’s going to be liable for the excess and a “black mark” for a claim.
I think it opens a real can of worms, at the least they should come inspect the car quickly then after that any damage is on them.
Maybe I’m being picky but ultimately if the car gets damaged at any point before they collect it you know you’re getting the blame. Glad it all worked out in the end
