Even in standard-wheelbase form, the 7 Series can seat four adults in comfort. Rear leg room in the long-wheelbase version is considerably better, though – more than you could reasonably want.
As standard, you get a three-seat bench in the back, which we have yet to sample. We have, though, tried the (long-wheelbase-only) rear seat comfort package, which gives you two separate rear seats that electrically recline. For those who want to get properly comfy for an afternoon snooze, the rear seat comfort package also gives you electric sunblinds and a footstool so you can really stretch out.
Whichever version you choose, the boot can comfortably accept a collection of suitcases. Be warned, though: the plug-in hybrid 745e’s battery removes a considerable chunk of boot space. There are also no folding rear seats, just a ski flap for long items. Still, are you really going to go to Ikea in your 7 Series? Scratch that; are you really going to build your own furniture?
