I think that my Lxx Char-G has the best body of my lot. It was nicely painted, cool decals, and good shaping. Next in line is my Shen, which had too many decals, but after removing most of them, it's pretty nice.
The Z-cars have the worst bodies of them all, IMHO. Minimal detail and a "squashed scale" perspective. I ended up getting a clear body for my Z-car and that's kinda cool. Oh well. My $ 0.02.
