I have owned a manual AC for 8 years, but have only been passenger in 4200 & GS.
I also now have an early-ish QP 4.2 so my experience might be relevant, given that I have same engine and gearbox as 4200cc (faster changes on Sport GT
)
The 3200 is intoxicating, like riding a rodeo bull when at full chat, but can also tootle thtough town like an Amish horse and buggy. Nobody in the general population sees a 3200 as any threat or a hooligan-in-waiting. It does however threaten to "kill me" every now and then, but only in a good way. Very edgy and demands total concentration to drive fast. Still a sumptuous place to go sit and relax. Proper Jekyll & Hyde.
The 4200cc engine and box is totally different, almost as fast but much more "show-off". The noise is great and suits a mildly updated exhaust, revvingto 7500 rpm is epic and the cam kick at 5000rpm was a nice surprise. The looks of the vanilla 4200 don't excite me, even thoe 15 spoke wheels look plain in silver. Maybe Ferrarri temed the 4200 to tempt back those 911 and M5 customers? Would consider a spider though, should always have one open top car in the fleet.
I only buy cars I
love, rather than like / want / need. Hence I will always own the 3200 and QP (rather than 4200 / GS / GranTurismo)
