I haven't had an issue so far but don't understand why overall storage space is so limited in the Giulia. I'm coming from a 2010 Saab 9-3 which is actually a little smaller dimensionally but had much more room in the trunk including a full size spare. The glove box was easily 3x the size and console storage was a good bit larger too. I could understand in a Honda where materials are noticeably thin resulting in high road and wind noise but the Saab felt solid and was actually quieter than the Giulia.
It is almost identical in size to my Mazda Protege. Compared to the Protege the major difference is that the "floor plan" is nearly square, making it difficult to put long things in it. Reference the threads discussing loading golf clubs.
For a sedan, I think there's plenty of cargo space in the Giulia. I've made some big grocery trips and other types of errands and never once ran out of room or wished there was more room. Plus, with the fold down rear seats, I've even hauled some large shelves from Costco and other hardware from various places. If it doesn't fit in the Giulia, odds are you're gonna need an SUV or a truck, not just a sedan with a slightly bigger trunk.
Depends on your needs. Things like errands, short weekend trips are fine. However if you thinking more like the mob I would say it's cramped for a live adult, especially if they are not willing to go into the trunk.
Previous car was a BMW E46 and the Giulia trunk feels like it holds a similar amount. Adequate is the word I would use. I do find myself making use of the fold down rear sear which is something my E46 didn’t have. The space under the trunk floor mat is disappointing to me but after looking under the Giulia is clear where it went. If 4 adults were going somewhere by air with luggage this wouldn’t be the car to take. But then would you really leave your Giulia in long term parking?
We leave Giulia at home in the garage when flying to Nihon and take the shuttle express to the airport. For most purposes the trunk is just fine for us. There's also the back seat, no passengers. You'd have to be nuts to park a Giulia in any public garage in the Seattle area.
I understand that the Giulia's don't sell very well in Sicily. Only room for two smaller bodies.
The manual says maximum cargo weight of 150 pounds. I put 100 pounds of electrical wire in the trunk and found that Giulia really wanted to wag the rear end even with this relatively modest loading. I think that limit is more significant than the space.
