Let me first suggest something that MAY seem like a criticism of Jaguar's XE, but it's not:
Go through the instruction manual and test every one of the features you read---decide to test NAV traffic announcements on one trip, Cruise-control and Auto Speed Limiter on one trip, then Meridian speaker settings and USB reader on one trip, Bi-adaptive xenon headlight movement another trip, and so on... until by the time your break-in period is over, you've had the chance to spot every item that may be functioning dubiously. That includes warning lights on you dashboard, because this car is very good at giving you messages that should be investigated.
A lot of owners have collectively identified odds and ends things that occur with the XE, most of them niggly little annoyances, but a few important items to catch if you spot it happening in your model.
This is YOUR Jaguar-----make it flawless.
Second, enjoy this car immensely. It's not like the typical Mercs, BMWs, and the rest. There is something so danged FUN about being on a road with this thing, that validates trading extra luxury inside for extra spirit and edginess on the pavement. All I want to do each day is get out of work and commute home. To WANT to Commute!! That sounds insane. But 40 minutes of my commute is in the XE.
