I think you might already be too late Sean as the diesel, AFAIK have already been removed from Motability.
Petrol, petrol Hybrid and PHEW’s are still there be it with larger AP’s and I was very interested in the ST X Line Kuga Hybrid myself and was attracted by the 50 MPG user are getting out of the petrol Hybrid but unfortunate for me the boot was just over an inch or two too small for my scooter so did not order.
Reading Brydo’s thread above I would say the removal of the diesel Kuga is a permanent thing.
