I have ordered an Allspace and had the same concerns re the rear hatch
The UK price list which lists the standard spec for each model does only list the “Match” as having “electric opening” on the rear hatch.
Only models from SEL up list a fully functioning rear hatch.
There wasnt an option to add it and I just hope OBD11 can do it. The OBD11 app does list the function as addable on the allspace.
