Has anyone ever driven the new M6 combi?

Moin together, maybe someone has already driven the new Mazda 6 station wagon and can describe his impressions of space/room feeling in particular? Since now sliding doors are no longer absolutely necessary, I would like to switch from a van to a station wagon or SUV. Especially important to me are the space conditions in the rear (fair itself 1.98 m and the children are not exactly small with 1.95 + 1.75m). The space conditions in the new V70 (our previous favorite) are unfortunately at full speed. So far, the space conditions were only good enough in the rear of the Santa Fe, Outlander/C crosser. Falled out already Tiguan, X3 and old C5 combi, as well as the old V70. Passat, Mondeo, new C5, and A6 are still in sight. Greetings from the north Marten
