Cadillac says 'no' to Ultra Sedan

All of you waiting, checkbooks in hand, for Cadillac to release their $100k-plus uber-sedan are out of luck. According to Automotive News, GM has officially put the project on the shelf after spending quite a bit of time judging the market. Ultimately, they decided the world isn't quite ready for a Maybach / Rolls Royce / Bentley competitor from a US automaker. So, no production version of the Sixteen concept after all.
