Reading my current Motability contract dated 7th March 2023, it states in the duration of hire.
The hire term is for a minimum of three years on the start date of delivery of the vehicle (the Minimum Hire Term) , but continuing thereafter until the expiry of a period of twenty four months following the Minimum Hire Term (the Maximum Hire Term) or the date on which this Agreement is terminated in accordance with the terms set out in Contract Hire Terms and Conditions.
What gives Motability the right to change terms in the agreement without prior notification.
A law unto themselves.
