yeah FAV is cousin of WildOne... i grew up with W1.
However W1 chassis tub is black with lexan body, FAV has beige tub & hardplastic top. Also the suspension arms are narrower on FAV and the W1 has better shocks.
Off topic I know, but who really cares that theres yet another 4wd touring chassis when you could be saving up for one of these - http://www.youtube.com/watch?v=G7YG22z_GRQ
