Is the Ferrari 599 GTB Fiorano a good investment?

The thesis

Only 30 factory manual 599 GTBs were built globally, with approximately 3 confirmed UK RHD examples—making this the rarest modern V12 Ferrari with a gated manual. The last manual GT Ferrari, it sits at the intersection of three powerful collector trends: end of naturally aspirated V12 GTs, extinction of the manual, and ultra-low production. Recent auction results show the final chassis (#187007) estimated at £750k–£850k. Manual conversions (£70k+ cost) are appearing at £115k–£195k, but factory cars command substantial premiums and are almost never traded.
