It's on the vin plate under the bonnet top right of the fire wall. There is a list of all the Copen paint codes in one of the service manuals too.
I'm looking for some silver touch-up paint. there's a big stone chip on the A pillar that I want to 'de rust' and tidy. Any known stockists?
There is a local spares shop near me that makes little bottles of touch-up paint (with brush) to order for £10. I think Halfords also provide a similar service. Rex.
