Toyota created an all-wood roadster concept

Toyota Setsuna’s real time-machine capabilities come in the form of a wooden body that ages through time as well as a 100-year meter in the dashboard that ticks off every hour, day and year that has been on the planet, Mashable reports.

The idea is that families who connect with the car will make memories in and around it. The clicking of the 100-year meter as well as the visible aging of the car is aimed to remind family members, as the car is passed down through the generations, of the significance the automobile has in their family.

Setsuna has been designed with both a fully wooden frame as well as replaceable wooden exterior body panels, which age and wear differently. This adds to the patchwork heirloom feel of the vehicle as well as its ability to be repaired overtime.

Toyota designed and built Setsuna for Milan Design Week that runs April 12 through 17.
