To my knowledge the Toyota Avensis, was never on the Motability list and was within the price limitation. Toyota were never known for including their larger saloon/estate cars on the list, however who knows, you could try asking Motability, sometimes they will tell you in advance, it seems your luck who you talk too.
I was told last year by Motability that the new Volvo V60 would appear, probably in January 2019, however it never did, it was just as well I never held off.
