Trouble with insurance on Japanese WRX S4 import- need advic

[JDMadrid]

Hi all,
I’m 27, full UK licence since 2018, 6 years no claims, and looking to buy a Subaru WRX S4 (2.0L 4-door saloon) imported from Japan and already registered in the UK. My main blocker is insurance.
Here’s what I’ve tried:
Compare the Market: shows the car as a Subaru Legacy diesel, even with the new UK registration plate
Japcover: model not on system
Brentacre: need to own car for a year first
Admiral: WRX S4 not on their system
Adrian Flux: quoted £1.7k–£2k annual (way higher than expected)
Howdens & Keith Michaels: awaiting response
Questions:
Is this insurance difficulty because the WRX S4 is Japan-only?
Or is it just a case of waiting for the DVLA to update the car details?
Are there any workarounds people have used, like insuring it as a UK WRX STI since they share specs?
Any tips on brokers or insurers who will actually cover a UK-registered JDM WRX S4?
Any advice or experience would be hugely appreciated—I really want this car!

Probably just youngish and an import.

Probably worth trying a few more specialists but might be worth sucking up one year in the hope that it's more reasonable after a year.

If you really want it that is.

Keith Michaels insure my jap import Imreza for what it's worth. I think they only cover imported or modified cars.
