Toyota's new concept car is a bit of a puzzle

Wood dash, wood wheel ... wood everything.

Toyota's new concept car, the Setsuna, is a sleek roadster featuring 86 handmade panels of Japanese cedar put together without nails or screws, but instead using Japanese interlocking techniques. That may sound more like a puzzle than a car, but the idea is to make it so the panels can easily be swapped out when needed.

Now, the battery-powered Setsuna's range is just 16 miles and its speed tops out at 28 mph, so this car is an heirloom, not a supercar. That's reinforced by its dashboard clock, which counts the number of years, up to 100, of family ownership.

And really, who wouldn't want one passed down to them instead of that old grandfather clock?
