I’ve an A4 estate and a Fabia hatch parked side by side on the drive. The Fabia Is narrow but that’s a real benefit in car parks and whilst there is more boot space in the A4 it’s still only just about possible to get a bike in with its wheels on I never do it’s much easier to take the front wheel off. For passengers the Fabia feels more roomy front and rear probably due to the higher roof line and less bulky seats/trim.
S’pose the non vrs Fabia could look staid to anyone who prefers a more phalic design personally I like the functional design, not just the exterior but all the knobs and switches are just right.
All personal choice stuff really but a Hatch Fabia is ok as a bike car, look at one next to Astra or similar there bigger than you think, you’ll still be taking both wheels off in the hatch though, the estate version will be better but possibly even harder to love if you like you cars pointy.
