Can some please help ?

Hi,

Providing the letter / email is genuine.....

Motability are refunding part of the Good Condition Bonus early to help with the cost of living. Details can be found here:
Good Condition Bonuse

This is from the Motability website:
'In reviewing the Scheme this year, we found that customers are taking such good care of their vehicles, we can pay £350 of your Good Condition Bonus early. We hope this payment can provide some help with making the most of your vehicle during a challenging time.

The remaining amount will be paid at the end of your lease as usual for vehicles returned in good condition. This will be £250 for a three-year lease, or £550 for a five-year lease.'

We have received our £350 this week. It is across the whole scheme.
There is no need to worry.
All the best.
