Out of interest, what happens between now and arrival of any new car? Does insurance cover you for a hire car?
Provision of a courtesy car isn’t always automatic under insurers motor insurance policies; with some insurers it can be an optional add-on. So, if it is an option and the policyholder hasn’t bought it, then they wouldn’t get a courtesy car at all. Worth anyone checking their policy to see if they have have this cover if it’s important to them.
Where a policyholder does have courtesy car / hire car cover and their car is stolen, it is usual for most insurers to place a limit on the number of days they will provide a courtesy / hire car - typically 14 days or until the claim is settled, whichever is the sooner.
Just thinking of new order lead times - can’t see insurance been happy to cover 3-6 months because you ordered something new.
They won’t - once an insurer has settled the claim for a stolen / unrecovered vehicle, they have no further obligation to provide a courtesy / hire car; their policyholder is in possession of the claim payment so is in a position to get a replacement car.
If I was in this position and didn’t have a second car I could use, I’d buy an old banger to tide me over until my new car was delivered.
