This is the most endearing feature of the entire Transporter range. You can do just as much or as little as you want. It's great that there is just so much choice out there to enable everyone to still retain some element of individuality. And the most important thing to remember is that; beauty is in the eye of the beholder. So do as much or as little as you want, it's your bus, and it is only you that needs to be happy with it. Besides
@Buggirl you've got all those stickers and Gen 6 badges going on, so even if it's mainly stock, its still unique.
