I see X3s all over the place. They've completely replaced the 3-series as the BMW of choice for clueless drivers that want a Roundel, but think Roundel is a type of doughnut. Not saying some auto enthusiasts aren't buying them, or enjoying them, but in the last couple of years I've noticed that if a BMW is going to not signal and cut me off and make a left turn from the wrong lane, etc, odds are it's an X3 and then the next usual suspect is an X5.
They must be making BMW a ton of money.
