I looked at 3 different srt's before I bought mine. Two had water leaks coming through the wing panel where it is attached to the car. Make sure there is no sign of water under the panel that covers the flat tire pump. If you see any sign of moisture there, go further to make sure there is no water in the area that holds the power door lock actuator. I still bought one of the cars w/water leaks because the price for the car was great. I fixed the problems and it cost about $500. It would have cost more except the XF Forum gave me great advice and I was able to buy some parts that saved big $ from members of the XF Forum. With that kind of miles on it one thing you should do if you are not sure it hasn't been done it to change the filter/fluid in the transmission. I believe it is supposed to be changed at 80k miles. It is a great car. I hope you get one that doesn't need much.
