Welcome to the forum
Is yours a coupe or convertible?
I have a convertible and I have noticed there is always a drip down the outside of the front windows which seems to be from where there is a fold point in the roof. Very occasionally I have had a couple of drips (of water) inside, but nothing major.
As the others have said, check the seals, check that the windows go up properly and if yours is a convertible, check the roof for any signs of damage.
