So what is the deal Merlin - saw you post the above in another thread? Have you thought about asking for your money back, getting your car to how it was - and be done with this?
If they have treated you poorly (and you are one of the first customers who should be treated like a VIP) - how are they going to treat you if there are issues down the track?
Rather than a lawyer - have you thought about the small claims tribunal in your state? Far less cost and still very effective as you are suggesting you have not got what you paid for (and the value is less than $7500).

Another question I have is why they even considered the Civic Type R project before they had concluded the Euro project.
