I've owned my DD for around 18 months and have already racked up 30K miles in that time (90K + total).

The Bad:

- Killed the rear end at the dragstrip, but that was expected. Proved to be a great excuse for me to buy a Wavetrac.
- Cupped tires (I'm blaming it on the inability to rotate them).
- Cup holder erection. Proved to be a nice excuse to get a usable cubby.
- Leaking hatch / spoiler. Simple and inexpensive fix.

The Good:

- The car is very reliable. With over 90K miles on the odometer, I had no qualms with driving it 1,400 miles in 36 hours last week.
- Very fast for the investment. With a few mods low 12's high 11's is attainable and expected.
- The XF is very solid, and doesn't feel like a junky econo box.

The car still gets plenty of looks and compliments, especially at the track. It's always nice to see how intrigued onlookers are at how quick these things are and how well they stand up to the newer heavy-weight sports cars.

All in all, I'm very happy with it as my daily driver. And yes, it gets winter duty also.
