I have my '05 X5 3.0i for 11 months now, 13,500 miles, no major problems. One of my interior light bulbs burnt out, some condensation in my headlights one week after posession (went away by itself), and one night, my headlights turned off when I stopped at lights or stop signs (problem also went away by itself). Other than that, no other issues. Really enjoying the car, and you will also. Have fun with it.
