 I bought my car back in June '06 used with 39K on it and now it has 52K on it. I haven't had any trouble mechanically on it except for as soon as my warranty expired my CD changer broke, but I hear that's common with all in-dash cd changers. I had to replace every door panel b/c the leather was coming loose, but that was all warranty and the Infiniti dealership had not seen that before.
