It should also be noted that as of 2015, the average age of a passenger car in use in Europe is 10.7 years, with a mode of around 12 years, and max 17+ years. Out of a fleet of 252 mln, 123 mln or about 50% were 10+ years old in 2015.

Same for light commercial vehicles, and even worse - at 11.7 years average - for mid and heavy commercial vehicles.
