If a twin coil pack setup my money is on it being 1108cc, and me being correct all along (its been bugging me that its a 999cc injection Selecta, when I've never been aware of them existing).
Only other way is Selecta vs Selecta drag race :devil:
:devil:
I've got a feeling you're almost certainly right. It's more likely -- from my (limited) experience -- that ePER is right, and it's been misregistered at the DVLA, because of the transition from 999 (carb'd) to 1108 (injected) Selectas....
Until then, I shall be valuing it at several squillion squid: as it's the only known 999 cc injected Selecta (impersonates Mr Clarkson) in the world....
