1 of 39! Rare BMW 502 V8 Cabriolet from Baur This BMW 502 V8 is one of only 39 of the exclusive BMW 502 Cabriolets realized at Baur, in which the Hautevolee liked to show themselves. The Baur company – based in Stuttgart – built 39 Cabriolets of the BMW 502 for well-heeled customers for whom a normal BMW V8 limousine was too ordinary. Around two-thirds of these convertibles probably still exist, so they are rarely seen.
