Always thought the Mitsubishi i was a bit of an under-appreciated kei car.
Most people will be familiar with it as the i-MiEV electric version, though versions of that sold in the US weren't proper kei cars as the car needed lengthening and widening to meet US crash regs. Which is also why it looks like it's eaten a few too many pies and why some of the neat detailing on the original car, like the bulging front arches that extend past the nose, disappeared.
I think it's a novel design. We're so used to seeing boxy kei cars that a completely curvy one seems unusual, but the use of space is still pretty good - I've sat in a few at motor shows (never driven one) and while quite narrow it does feel airy inside.
Early ones did get a proper kei engine - 659cc inline-three, with non-turbo and turbocharged options - with an electric motor coming later. Rear-engined, rear-wheel drive, which makes it fairly unusual.
I particularly like the Se-Ro concept that preceded the production car though, which had a kind of 1930s art-deco/streamliner vibe.
Would definitely daily the Se-Ro. And I'd like to at least try an i.
