thats right at the moment @kezo, for example the juke hybrid ive ordered at todays price is fixed at 72 per week and a £623 ap which as you say will give me about £28 a month rather than total allowance which would give motability any future increases.
however once the increase is ratified i suspect the ap will fall to 0ap and the weekly amount will increase to almost total allowance. and the differential will return to roughly £1200 on the ap’s.
so by april if wpms goes up to £79 odd and a civilian ap is £1200 wpms will be zero but the wpms recipient will be paying more weekly over the 3 years evening things out
