We didn't bother to attend Jaguar's press conference today at the 2007 LA Auto Show, mainly because the only car it had to show off was the North American debut of the 2009 Jaguar XF. Yeah, been there, done that in Frankfurt last September. But Jaguar did announce a nice nugget of news at its presser, which is that the '09 Jaguar XF will start at $49,975 when it goes on sale March 1, 2008 in the U.S. That's for the "standard" XF with the naturally-aspirated 4.2L V8. An uplevel version of the NA V8 model called the V8 Premium Luxury will base at $55,975. Finally, the Supercharged XF with the 420-horsepower supercharged 4.2L V8 will start at a mighty $62,975. While all prices include a $775 charge for destination and delivery, that's a heady brew to swallow. Will Americans go for such an expensive Jaguar sedan considering the brand's performance in recent years? That's the make-it-or-break-it question we can't wait see answered.
