I’m going to guess there will be negotiations with the car companies and recalculations of APs hopefully in time for the Q2 announcements.
I feel it’s wider than just Motability though, many people who were about to buy an EV now find that their car no longer attracts the grant, so, it’s upto the manufacturers to stop their blatant profiteering on fairly low end EVs by adding a few essential items as options to boot the price up (Peugeot, you are guilty of this).
Maybe we might see some reductions in RRP so more cars qualify for the grant.
