This is the Toyota Setsuna, a concept car launched at Milan Design Week
It includes a clock that reads up to 100 years to mark how long you've owned it although it may feel longer since it only does 28mph and it's range (for it is electric) is just 16 miles.
It is made of Japanese Birch and Japanese Cedar which just sounds a bit classier than carbon fibre or magnesium/aluminium alloy. Mind you after 100 years and a couple of coats of Dulux Non-Drip Gloss it may not look so good. Rust should not be a problem although I suppose woodworm could be an issue.
And what happens if it is involved in an accident?
I don't think Halfords have a carpentry department.
