The solicitor has sent me down the Consumer Rights Path. They have quoted the following in the letter they sent me to send...
In these circumstances, I am requesting a repair or replacement (Section 23).
Section 23(2) provides that any remedy must be provided within a reasonable time, without causing significant inconvenience and whilst the seller bears the necessary costs. If this cannot be done or a further fault arises then I will be entitled to reject the item and obtain a refund under Section 24.
As a direct result of your breach of contract I have suffered consequential losses, such has having to use an alternative vehicle to get to and from work and for other essential journeys. I have been paying £xxx per month for a vehicle that I have not been able to use.
Consumer rights are separate and distinct to any warranty or guarantee and cannot be restricted or excluded as per Section 31 Consumer Rights Act 2015.
They are enforceable for 6 years after purchase against the seller.
They said we will see how they respond to that and then subject to their comments proceed accordingly.
