I have 254,681 miles on my CL and it runs like a dream! I bought it used in 2004 and it had just around 100,000 miles on it then. I'm not sure what the guy before me did to it in respect to repairs and such but I have not had one problem with the engine since I have had it. I replaced a bearing once and have had some trouble with the electrical... my volume turns up when I turn it down sometimes haha, but it's still an amazing car. The stereo is sick! I love the car.
