I'm building one, or to be more precise I'm using it as a base for the Legend IIID conversion

It seems to be quite accurate regarding the wheels and suspension. In fact the "rubber" part of the road wheels are separate black plastic rings that snap into the wheels (very convinient). I'm using the latest generation of all steel wheels from the Legend kit too.
The spacing of the wheels seems very correct and the top deck (when compared with the Legend kit) has very fine and crisp detail.
The same for the turret and side armor plates.
If you want to make a better kit , Legend sells several parts separately (side armor) turret (several versions) etc etc.
The ball and chain armor on the turret is nade of solid white metal parts on the original kit or, again, Legend sells a kit for doing them (60 in total I believe...)
Anyway I think that it is an excellent kit OOB.
If you want it a little better, Eduard makes a detail set for it.
If you want to go even further, Legend is the way to go.
All variants and options are available from them.
