Hi Craig,
Both Gordon and Mitch are talking absolute sense.
The £1000 discount you mention is for buying new. While it means it cannot be directly read across to Motability, it does mean that the dealer is trying to shift cars. So you’re in a good position.
If they do not offer anything, look for Motability deals in other dealers and ask if your closest dealer will match it.
Be prepared to walk away but leave your contact details for in case the dealer reconsiders.
Good luck. ?
? I will be remembered for nothing but had great fun doing it ?
