As vice president of marketing at the largest Porsche dealer in the country, Shiraaz Sookralli personally handled some of Champion Porsche's most valued and deep-pocketed clients. Over the last year, he collected over $2.5 million in customer deposits for dozens of the company's ultra-exclusive 911 GT3 and GT3 RS models.

There's only one problem: The cars never existed, the money is missing, and Sookralli just vanished without a trace.

That's according to a lawsuit filed by the dealership against Sookralli in Florida's 17th Circuit Court last week, which first surfaced online in an explosive thread over on Rennlist, one of the most popular online forums for Porschephiles. Beset by financial woes, Sookralli allegedly created a shell company called "Champion Autosport," produced fake documents to trick buyers into thinking they were placing a real order with the dealership, and diverted their money into a secret bank account—one that's since been emptied out. The documents also state that Sookralli admitted to all of this in emails and phone calls with Champion Porsche, though his whereabouts are unknown.

With more than $2.5 million gone, it's on track to be the largest fraud case in the history of Porsche Cars North America, once the dust has settled. The scale of the fraud makes criminal charges a likely development.

The dealership claims to have had no knowledge whatsoever of Sookralli's actions prior to his disappearance at the end of August in the lawsuit. But that explanation isn't sitting well with the would-be owners who have neither their cars nor their cash—and a previous suit involving Champion Porsche, Sookralli and anearly-identical scheme is boosting their suspicions.
