The important thing to note is these cars have already depreciated by a significant amount. So its highly unlikely that u will end up losing a lot when you sell it. For example, Puntos were sold as Brand New at 3.5million+ mark during 2007, but now they are going at around 2.3million range. You can get a 2007 one for about 2.2 - 2.3. But you need to be patient whenever you sell a Euro. Also the key is to find one in very good condition.
I owned a Punto sometime back, which I sold because my better half couldnt get used to the dualogic gear system. I actually sold it for slightly higher than what I spent for it.
