Johann de Nysschen, Cadillac's new chief, sees ultra-premium cars in the General Motors luxury brand's future. He said the brand could roll out quarter-million dollar cars by 2029. "It is too early today for a $250,000 Cadillac," said de Nysschen in an interview on Wednesday at the Los Angeles Auto Show. "Fifteen years from now, it won't be." Cadillac's current flagship car, the XTS sedan, tops out at around $70,000, far less than the top end of BMW and Daimler AG's Mercedes-Benz.
