There was someone who posted about three times and then was gone, she said her SRT had 176,000 or 182,000 or something like that. She said the car had cost her only tires and oil changes.
I personally drove a base roadster abotu a year ago with 120,000 on it - the 6 speed shifted way better than ANY XF I have ever driven - these cars NEED some miles on them!
I suspect we ARE CERTAINLY driving 250,000 mile cars, maybe much more than that. Mine has about 63,000 on it now... I plan to have it for a LONG time... provided it doesn't get totalled like so many others.
