The long version

The turning point wasn't organic appreciation, it was Ferrari's own decision to go turbocharged next — the moment buyers realized this was the last naturally aspirated mid-engine V8 they'd ever get from Maranello, and the ones who bought in specifically for that reason are a different animal from the original-era owners who just wanted a modern Ferrari. The Speciale variants sit at the sharp end of that divide, screaming to 9,000 rpm and increasingly too valuable for some owners to use that way. Values have swung hard over the past decade, evidence of real speculative interest layering on top of a car plenty of people still genuinely drive.
