Wow! Who the hell spends half a million bucks on a Bimmer? I can see the M8 and Nazca ultra rare concepts fetching that price, but the rest? Glorified 5 series, 6 series, X5 or X6 with some ugly body kits, paint, wheels, and FI engines? And somehow that makes them worth as much as an Aventador or F12 Berlinetta?
