isopropyl alcohol ? Its a common issue of cars from this era, the Fiat Coupe had a dash panel that would go sticky. The Ferraris of this time even had the same issues.
Weren’t they rubber door handles that used to crack and then fall apart? I remember a friend having them on a brava or maybe it was a bravo I forget now, but he was moaning about the state of the door handles circa 2006
