The modifier b+b Auto, founded in Frankfurt, 1973 by Rainer Buchmann and his brother Dieter, caused a stir in the European and international car scene of the '80s. Their technical innovations and spectacular design made them stand apart from the crowd. Initially focussed on Porsche cars, b+b established themselves as a name to be remembered when they presented their Porsche Turbo Targa with prismatic coloured varnish at the Polaroid stand on Fotokina 1976 Cologne. At IAA Frankfurt 1979 they launched b+b CW 311, a contemporary modification of the legendary Mercedes 300 SL. Mercedes-Benz was so enthusiastic about the car that they allowed Buchmann to continue using the Mercedes star as a brand logo. During the 1980s, b+b was one of the most successful modifiers of production cars. They transformed off-the-line automobiles into individualized luxury vehicles for those who could afford it - customers from the Arab world, celebrities from the Jet-Set, and many more... However Buchmann's real passion belonged to the area of electronic innovations. The money he earned with his tuning activities was invested into research in this field. He was the first to think about centralized door locking by means of remote control as well as park distance control and he invented the first car computers. In 1983 his multi-function steering wheel was protected by patent. This comprehensive book, produced in close cooperation with Merck Group, one of the world's leading chemical companies for whom Buchmann popularized a new and special kind of bright enamel varnish, presents the complete history of Rainer Buchmann's technical and entrepreneurial achievements.
