BMW M5 CS
Reference — shown, never scored
Why 7.4: One-year run, universally called the best modern M car — which put collector pressure on a sedan built to be driven. The ones in use embarrass supercars; the rest are appreciating in bags.

The long version
BMW built about 2,500 of these worldwide and priced them like a statement, which guaranteed two very different buyer types showed up on the same order sheet — enthusiasts who had waited a generation for a proper M5 and collectors who read 'limited run' as an investment memo. The wheel-cover-wrapped, plastic-still-on examples that surface at auction are the second group's work; the ones with brake dust and a for-sale ad mentioning lap times belong to the first. Both cohorts are betting the same way on scarcity — they just disagree about whether to enjoy the bet while it plays out.
