We had this conversation in another thread, almost post for post, but I will recap what I said there - when I was looking for a new wagon in later 2019 (ended up with E-Class estate), the only estates I could fit my large E-Sommet in where the Skoda Superb, E-Class and Volvo V90.
5 series and A6 a no go (was surprised at 5 series as my old E39 could fit it in). Didn't try a Passat as presumed it would be like an A6.
What I was looking at was a car where you can literally chuck the whole bike in, no mucking around with getting the right angle, and also with no load lip - the e-class does this.
I had a c-class estate before and you could with some fing and blinding get the whole bike in, but it want a quick job, and would inevitable scratch up the car inside, so I just took the wheel off.
Of course MPV's will do the job easily, just my Mrs won't have one, and she drives the car day to day.
Of course the downside to the big estates, is they are big cars if you live in town, but I live out in the sticks so no problem.
Having said all that my main bike transport is my CLA estate, much smaller, but I put the bike on the roof, less facking around, no mud in the car, but inevitable one day I will drive into a restricted height barrier with the bike on
