So it seems I took the plunge, and traded my F30 for a i3s - Didn't put pen on paper yet, but the car in question is a grey i3s, with brown leather interior (BMW Design suite).
Didn't see it in the flesh yet: May be a bit worried if the brown interior is a tad on the dark/gloomy side, but the light/beige interior options is probably a bit too prone to spots.
Should have in a week or two... Excited !
