I drive a Skoda Octavia wagon my 2018, ordered it on purpose with a door in the back seat (even if the back seat is a 1/3 2/3) and a ski carrying bag. Great car to drive in winter conditions (even if I couldn't get the 4x4 version) and, to my standards, roomy as well.
If I am alone or just need to commute from home to the home-hill, and 2-3 pairs of skis are involved, then the skis will get inside the car in the bag, which comes with a "safety belt" to be looped to the top of the seats to avoid it to slide through the car.
If I'm not alone and/or more than 2-3 pairs of skis are involved, up comes the roof top box.
Edit, a picture is worth a...
