<<Does anybody knows whether the factory would take it back (at their cost)to look at it deeply ?>>

Jean Pierre, I am sorry to hear about your problems, what a pity that you are unable to reliably use such a stunning car.

In '04 When my +8 had to be returned to the factory under warranty, I had to arrange to ship it to Portsmouth, and they sent down a driver to pick it up from Portsmouth and take it to the factory. But in your case, as you are so far from a port and the car is not reliable, I would have thought that it would be reasonable to have it shipped all the way.

But your dealer should "own", this problem not you
