How far ahead can you sort a lease? (next April for iPace?)

[Tiggsy]

Next April I'm going to lease an iPace (via my company under the new BIK rules for EV). All my last lease cars (must have had 10 plus) have been sorted real quick - I pick roughly the car I want and take what they have. Even my latest (a V60) which was a factory order, came within weeks.

So...do I start looking at deals next Feb/March or is the world of EV's a bit different regarding fallibility?
