As you probably know, the Toyota iQ microcar is headed to the U.S. as a Scion. Now, Motor Trend has found this rendering in a Japanese car magazine. It looks to be an artist's interpretation of what the iQ convertible might look like. There has been talk of other vehicles based on the iQ's platform, so this might not be too far off. I'm sure the ginormous wheels and aggressive body panels would get lost (might get lost?), but it looks pretty cool to me.
