The rear quarter panel looks too round for being a 206, and so does the headlight. But it definitely is silly riced . I agree with @Blijo and say Vauxhall Tigra since Opel was wrong.
Believe it or not, but they actually do! But i think it was only the second generation Tigra, which means that this is not a Holden.
It's not a Corsa, even though those photos were posted on a Corsa forum. It's a Tigra as mentioned (which is based on the Corsa B).
