The Mclaren F1. Simply put one of the most significant automobiles ever. Period. The market recognizes it's rarity and its exclusivity (1992-98 > 106 units). having sold originally for under 7 figutres, these cars, if they ever come for sale, are fetching 8 figures. The last sale I wrote on was a red example selling for a little over $10MM (HERE). As noted in the sale promotion material, this sale is expected to reach $12-14MM.
