Apparently they registered the name 430 instead of 420 around the world...? Though I don't put it past the car magazines to have just screwed that up totally (Car & Driver).
Common sense says that it should be the 420 after it's 4.2 liter engine just as the 360 is named after its 3.6 liter engine. the 430 has been registered in numerous markets suggesting the name 430. This must be becasue of the 612 Scagletti being named for a 6 liter V12 when it is actually closer to 5.8 liters. It must be a current Ferrari Trend. I don't remember where I read this, it might've been R&T or maybe C/D
I heard it was the 420 Monza. I don't remember the source though.
420 = 4.2 liter.
Personally, I'd grab it if I could, but I just hate the way Ferrari is heading with those fishtail looking taillights, first the Enzo and now the "420 Monza"?
