Don't buy an i3 expecting to get the same sort of space that you'd find in a BMW executive saloon – the load space on offer is more in line with what you'll get in a conventional small car. Indeed, the boot is actually smaller than a Ford Fiesta's.
It's just about big enough for a modest load of weekly groceries, but it'll struggle to cope with, say, a buggy chassis. The i3's narrow design means that bulky items, such as a stroller or golf clubs, will be fiddly to fit across the boot area, too.
The floor itself is pretty flat, though, and while it's quite high, that at least means there's no awkward boot lip to lift items over.
