Based on the Lamborghini Diablo, the Vector M-12 was the second production model made by the American car company after its takeover by Indonesian company Megatech. While a slightly less wild than the twin-turbo W8 that preceded it, the M-12 featured a 5.7-liter Lamborghini V12 making 492 horsepower — and was also built to order for the Prince of Brunei. The black exterior over red leather interior makes this M-12 particularly striking. Only 14 M-12s were made between 1996 and 1999, with this being the 12th. Rare and with a very high-profile history, this M-12 has undergone a recent refresh and shows only 2,160 miles. The car will be up for auction Later in March 2021 at Barrett-Jackson's Scottsdale event.
