Tonight Show host Jay Leno is a noted car enthusiast but his enthusiasm may have him in a bit of trouble. Bloomberg reports that Leno bought a rare 1931 Duesenberg luxury roadster through what has been called a "sham" auction while the elderly owner was suffering from dementia.. The car in question is a 1931 Duesenberg luxury roadster valued by its owner at $1.7 million. Leno paid $180,000 to the Manhattan garage, that said the owner, now deceased, hadn't paid his bill and sold the Dusenberg and his 1930 Rolls Royce. Wendy Lubin, daughter of late Macy's executive John Straus, has sued Leno, 58, his company Big Dog Productions Inc., and the Upper East Side Windsor Garage where she says the cars were parked for more than 50 years. The complaint filed in New York State Supreme Court in Manhattan says that the cars were auctioned off to satisfy "relatively trivial parking bills." They also says that they garage tried to confuse Straus with multiple bills and refusing his checks to pay the Windsor garage bills, and that they never contacted hi or his family. The plaintiffs seek damages of more than $1.7 million and return of the Duesenberg.
