It's about time Caddy got around to updating its flagship sedan, and update they did. The 2013 Cadillac XTS ($TBA) replaces both the aging (and hideously ugly) DTS and STS, breathing fresh air into the company's full-size lineup with all-new styling, the company's all-new CUE infotainment system — think multitouch and proximity sensors — and, surely, plenty of other goodies that have yet to be announced. Expect to see it in showrooms early next year.
