Your experience is your experience, but it sounds like you have not used any of the info on this site that could have saved you a lot of money. The XF is not a common car, so parts new or used are expensive. I did not want a car that is as common as a Focus or Pinto. I drive this car on weekends and it has delivered exactly what I wanted, It makes me smile everytime I drive it. I have not done the " Ignition Key fix" yet, but will as soon as I can loose enough weight to get under the dash. This is a great little car, can drive 80 MPH with AC on and still get 28 MPG, looks great, is fun to drive. When we go to the local ( Houston Cars & Coffee) shows it is one of maybe 5 XFs there among Porsche, Vettes, Mustangs by the hundreds. If you want salt grains then buy them, but I wanted something that everyone else did not own. We are so lucky to own one of these great cars, smile be happy.
It sounds to me like to you a car is just a car, but that is not the case with me. I love it and it gets treated as such!!!!
