I've always felt that the Jaguar's name has been diluted with the S-type and X-type as guised up Fords. Jagaur doesnt have the same awe as it did in the 80's reaching more exclusivity than even Mercedes. Don't get me wrong, the S-Type is a nice Jag, but the thought about it sharing a lot in common with the Lincoln LS leaves me :a:.
I'll take an MB E-class over the Jag. The 2003 E-class is hands down much better design than the boring current design. Here's some pics of it.
I voted the the M5 though.
