Their Dash 8-40CW probably is their best GE safety cab model, there seems to be a bit larger face on it.Their CN model, of GE's DC locomotive, is one of their best GEVO models, if not their best.
I have the newer 3.0 ACe, Hi-rail version; they dropped the roof mounted sun shades. I like that look better. It makes for a cleaner, taller, stronger appearance; basically... rectangular. That must look even better,with the fixed pilot.
I'd like both the ACe and the GEVO models, without sun shades. Less clutter, nicer visual impact.
It should be noted that the livery plays a significant roll, in determining how massive the front looks, on these two models. I find that fewer breaks in the base color(going with basically one color), makes for a more massive appearance.
