Importation of Car (Tunis)

Hello,

I have a question: Do anyone knows how much import duty I need to pay for importing a used car from Italy or Switzerland? Someone told me its about 200% of the value! But that sounds crazy. Does anybody have a link or an idea of where I can find a quotation. I understand that it depends on the model, the cc's the age etc... but I have those details all ready!

Thank you very much in advance.

Good week end
