You be surprised at how easy that job is, relatively speaking. The 458 Italia is even easier, as you simply drop the rear cradle out with the gearbox and replace the clutch that way. 2-3 hour job. Faster than most front wheel drive cars....but it’s the hourly labor rate that’ll kill ya with a Ferrari. :)
I understand Ferrari mandates some repairs be done only at the factory. Any idea of the rate?
