​​​​​​I'm looking for the best entertainment ROI not financial. Ferrari definitely wins that comparison. The more accurate comparison would.be new Miata vs used Ferrari.

IMHO capital that doesn't beat inflation should be liquid not tied up for months or years at a time. TBills, CDs and cash are simply storage places where money sits while the investor is finding a purpose for it. Cash is like short call, the purpose is being "promptly available" if needed.
