Show us some pics, as obviously some replicas are better then other attempts....

As a rough guide, a mint full replica (bumpers, skirts, bonnet, interior, spoiler, steering wheel and wheels) you should be looking to ask about £1000 - £1500. Although its a replica, there is a market out there for people who cannot insure a real cosworth, or who cannot afford to run one.

I also have been told that there is a lot of Irish interest in them, as insurance over there on the real cossie is sky high and near on impossible for most people to insure, so they look for cossie's in the UK.

Hope that helps.
