Used EV on PCP, have I missed the boat?

[Norfolkandchance]

I've been researching some of the PCP deals on used EVs, particularly Leafs but the best rate seem to have gone. My Nissan dealer tells me it is because the cars coming onto the market now are better, but I suspect it's a reduction in subsidy from manufacturers.
Is speak EV the best place to look?
Thanks
