I don’t know about the Fiat Bravo, but I know for certain, that the
Alfa Models built on that floor pan had holders under the front
passenger seat where little pieces of blotter paper went. These
contained “Alfa new car scent”.
These did not have the awfull vanilla tree odour, but underlined the leather and wood in
the car, even if it didn’t have leather… 
My dealer was shocked when I gave him the order number for replacement plates after
some years, they had forgotten about that item.
