I was given a complete, original vr v6 Berlina as a parts donor for my v8 Calais. Best of all, it was free.... Anyway, the car is complete and absolutely original. You could register it tomorrow. The Berlina has climate control which I have been told works. [I still have to check). The climate control in the Calais doesnt work. Is it feasible to think I could remove all the components from the Berlina and install them in the Calais? If so, what parts should I be taking?
