I bet your Bravo has a sunroof.

The Fiat Bravo suffers from a design in sunroof, the frame starts to split due to poor construction, material and age, and this causes water to drip onto the roof lining. It then collects up there and will swash around as you drive. You may notice mould patches in the top corners of the roof lining, wet carpets, seats and runs of water running down the windscreen under heavy braking. This is something you can't fix without spending alot of hours removing the roof lining, resealing the frame with loads of silicon and then putting it all back.

Without permanently damaging the car you can rub a thick amount of vaseline around the sunroof seal from outside. This will stop water ingress between the seal and the car roof. You could apply a water proof sealant around the seal, but this will look horrible. This also renders the sunroof un useable.

Now if your one of the lucky ones, the water actually might be coming in from under the roof aerial, you can remove the aerial use a water proof sealant under the aerial base and refit it. But 9 times out of 10 its the sunroof.
