Exchange of door rubbers useful?

Moin, was surprised that I have not found this in the SuFu yet My elk (V70 D5 EZ 02) now has 257 tkm down. For some time now it is a bit louder than at the beginning of our “relationship” (at 135 tkm) or as a new car. Well on my second car it does not reach by far At the driver and passenger door the door rubbers are no longer ok. In the upper area (to the back door) they are definitely broken. Can someone tell me about the cost of the rubbers? And what else I still have more interested, does it really bring a lot or has the engine also increased in volume over time and contributes to the larger part? There are just loud driving noises that disturb when cruising.
