Synopsis of commercial

An older man is alone, driving an older BMW M series car watching the sunset. As he drifts up the mountain (showing how drivers have control of this car model), he turns younger and younger, and his car becomes more modern. At the end, the viewer discovers these are two different people: it is a father and son driving the old and new versions of M Series and metaphorically passing the torch/creating a legacy. Final text reads "Legacy. Built by you."
