Question: Luggage compartment comparison 9-3I to 9-3 SportCombi

I just had something bigger to transport, and I was really excited about “the big hole” in the 9-3I. As a former Volvo combi driver I was used to being in place and had earlier worry about the “return” to the Saab. Today no longer How is the comparison between 9-3I and SportCombi actually? The ratio 495L (9-3I) to 419L(SportCombi) is known to be relative.The difference, however, is high as a theoretical value!
