Because after a few minutes it will be a second hand too, i prefer to buy something better and bigger for the same price. Same as my Iphone, bought it second hand 1 year ago and it's working like a new Iphone, but paid half of the price.
475 000 you have the Nissan March, 630 000 the Honda Jazz.
But for 600 000 in second hand you have something really better, normally.
And not, i'm not going to buy a second hand Honda Jazz pour that price
