There’s no need to panic. Once a new car has been ordered they can keep their existing car for as long as it takes for the new one to arrive – even if that’s 6 months or more. The insurance will be extended and the car can be serviced and MOT’d as normal. It must have a valid MOT when it reaches 3 years old, but when it’s eventually handed back it can have as little as 1 day MOT remaining. They can even extend the current lease by 3 months if they want to take their time choosing their next car. This might be useful as cars ordered in haste often turn out to be poor choices.
Thanks will pass this onto them it will probably come at a relief they thought they made have only gotten a 90 day extension or been left without a car till the new one arrives
I’ll also let them know about that extension they have a few requirements based on their current car so having that extra time would probably do them a world of good and make it as stress free as possible for them
