From Toysdaily, a comparison between the new Hover Pilder (or Pileder, says Bandai) PX-04 (based on theory by Shin Mazinger Z) and the old PX-01 in 2000.
In all the photos, PX-01 on the left, PX-04 on the right. As you can see, unfortunately, the differences are quite minimal, limited to the recoloring, a different instrument panel, and an appendix to the metal on the top of the windshield.
Looking at the series instead, something else would have to do ... I ristampassaro Bandai least the bigwigs
