Is the Ferrari 360 Challenge Stradale a good investment?

The thesis

852 built globally, 116 UK RHD. Current UK asking £450k–500k for ultra-low miles, average £181k. Lighter than Modena by 110 kg, 425 bhp 3.6L V8, last analogue Ferrari lightweight special before turbos. Tracks predecessor to 430 Scuderia/458 Speciale lineage. Despite small production, has not had the run of Scuderia yet—undervalued vs. later specials, especially pristine RHD examples.
