Importing From USA.... But.

[Allandwf]

Does anyone know how I would stand re duty etc. on the following.
Italian car, originally sold in Europe, European designation Vin No. , imported into USA some time ago. If I was to import back into the UK, would duty be payable, ie the 20% normally applied, or would it not as it was an EU car?
Trying to see if it is viable.

Thanks all.
