^Yes the Wigo will suffice... I've seen 650cc cars (Japanese Kei) that drove well with 5 people...

I was referring to earlier comments that the engine is too small for a 7 seater.

If ever this car makes it locally, sales people should inform possible buyers that it's a city car, don't expect too much when driving it in the highways...

I was in SM North once, Mitsu had an event (I was looking at the G4 (it was then new), I over heard a potential buyer asking the sales person if the Adventure drives better in the highway compared to the Innova (prev gen), sales person said yes!
