Some automakers are already selling 2020 vehicles, but how can this be?
I suppose an auto maker could unveil a future vehicle design or concept car, for display only in showrooms and auto shows, and say "This is the new model with a planned release for 2020." I suppose they could even sell preorders.
But if it currently exists in a dealership and you can drive it home today, then how can something already manufactured be a 2020?
Before something is made in 2020, 2020 has to actually come.
