I normally make it a rule to not buy outside of warranty too, but thankfully the Ferrari dealer stood behind their car.
It was a manual car, and I knew before purchase that the 5-6th synchro was bad, which they agreed to replace for me at my convenience.
When they took it in to do the work, they found shards of metal in the transmission, thus it needed a new transmission at $50k. It also needed new headers due to a known issue with the precats breaking up which can grenade the engine at another $10k. There were a few other bits too that needed doing which made up the last $10k.
Thankfully the dealer offered to pay for all that, leaving me to just pay for a new clutch out of good faith, so my bill was only around $8k.
When I finally got the car back, a week later the diff went bad, which was related to the new gearbox, so a new diff was needed at $20k, which, again, the dealer covered FoC.
These things can be eye-watering, and is one of the reasons I got rid of my Mclaren MP4 before the warranty was up, as it was horrendously unreliable with absolutely epic bills had I not had dealer support.
