Interesting. I entered a random french plate number on Autorigin, and the good thing is, it showed most of the VIN. This can be useful.

VIN : VF3MCYHZJKS19****

It also shows basic data, like these :

Carburant : Gazole
Cylindrée : 1499
Couleur : NOIR
Places : 5

Oscaro.com only shows a single line, like this : PEUGEOT 3008 II 1.5 BlueHDi S&S 130 cv.

A combination of both sites would be better.
