Looks like Fujimi did it again (in a positive sense). With a price increase of only 210 yen, you'll get these parts.
The interior sprue is very different (door panels, floor pan , dashboard etc.) The wheel sprue seems brand-new, and there are two extra sprues for the rollbars etc. and the seats, steering wheels.
This is going to be a great kit. Man, we should hold a F430 Challenge group-build or something.
