I am confused!

Hello everyone. I am confuse about buying a tamiya wild willy. There are 3 versons:

Wild willy 2000 kit:

Wild willy metallic special 2 kit:

Wild willy 2 xb rtr:
http://www.tamiyausa.com/product/item.php?product-id=57743

Are they all the same, just different colours? All I knows the differences is that, one is a rtr and the two others are kits. Any more differences?
