Honestly I'd say it depends where you live.
Last accident (DH hit a deer) in 2011 we were with directline. Can't fault them, they came and assessed the car, it was driveable, then came a collected it and returned it repaired.
Now with admiral and we were reversed into at some traffic lights.
First they suggested this all singing and dancing service Auxillis. That might have been okay if you maybe lived in a more populated area however, we are expected to take the car to be assessed and in for repairs and collect. The nearest garage the can offer is 45 min drive away and can't do the car hire so that would be separate, as garage is in the arse end of nowhere, the car hire wouldn't be near it.
Back to Admiral, instead we can use their preferred garage and pay them our excess, this time 30 minutes away and in theory they can provide car hire but not confirmed. But still results in 3 x 1hr round trips plus time at the garage and we both work full time.
Now trying to see if there is a possible plan C.
Now if it was our fault then I guess we'd be happier to just suck it up.
We live in a city BTW, just a very small Scottish one.
