Sales of traditional four-door family cars fell by 55 per cent between 2004 and 2013 -- from 459,041 to 208,462. Sales of the smallest city cars are up 122 per cent since 2004 -- from 36,171 to to 80,377.

In New Zealand, the SUV market is the fastest growing with sales up 27 per cent this year. Last month seven SUVs were in the top 15 for new-vehicle sales with the Nissan X-Trail in the number two spot.
Auto Express editor Steve Fowler said: "The rise of the sports utility vehicle has marked the demise of the traditional family sedan. The SUV is killing them off.
"The new SUVs are sports cars for people who can't have a sports car -- and everybody wants one.
"People like sitting up high in a commanding position -- especially if stuck behind a truck. You can't do that in a sedan. And they like the feeling of space."
Sales of compact family cars such as the VW Golf fell by 19 per cent from 729,690 in 2004 to 588,402 in 2013.
Sales of luxury cars such as bigger Mercedes models are down by 39 per cent in a decade, from 13,620 in 2004 to 8346 in 2013.
