The F430 is my current dream car and the only timeless design that I would keep for awhile!
The only cosmetic change I would make is minimize those huge black intakes with body color on the inlets adjacent to the grill inserts. Also, the bridge area should be body-colored between the inlets as well. Most of the guys/gals at Ferrarichat believe that those inlets and the Enzo rear-end detract from the nice uniform flow of the previous 360.
The F430 is a major change in design direction from the 360 unlike the evolution of the 308==>328=>348==>355==>360 iterations. I'm glad Ferrari didn't try to mimic the kit-car appearance of the Enzo up front.
