Wife doesn't like spirited auto driving, you don't always have to take her with you and if you do, just tell her that you need balance, sometimes a Sunday drive, sometimes more aggressive...hint, just start making the Sunday drives a little more aggressive every other outing. Outside of that, you need to bring her to a Dragon so she can see what it means to be aggressive.

You love your car, got it. Presuming your wife was looking for a different kind of spirited driving, you should have gone to bed as you can always come back to the forum to read about your XF.
