The yellow car pictured in the lead being driven by John Cordts was at that time owned by Bill Overhauser, and raced out of his WORLd team. WORLd standing for William Overhauser Racing Limited, with a d added to make a word. It had a long lineage, which, according to Martin Krejci, went: => A. G. Dean (1971) => {rebuilt using M8E-80-10} => Roy Woods (1971) => Bill Overhauser (1972) => Hal Whipple (1974) =>Modena Collection, AUS (1980) => Bruce Zeigler/Zeigler Coach Co., USA (1990) => Ernest Iaconetti (1997~2005) => Bruce Canepa (2011~2012) => anonymous, Chicago (~2014)
There were four M8Ds built, one of which was destroyed in Bruce's crash. One is in the McLaren collection, another in the Stroll Museum, and the third as described right above. The various M8Ds that pop up at vintage meets are either other models with M8D bodywork, or outright replicas, assuming the three originals are still with their owners as just mentioned.
