I just filled out my 2002 CR questionnaire for my 2000 4.4. I'm happy to tell them that I have had NO problems in the last year and "considering all factors (price, performance, reliability, comfort, enjoyment, etc.), would you get this car if you had to do it all over again?". My answer, "Definitely yes". So, fellow X5 enthusiasts, my reply may not be statistically significant but CR will hear that I am one very happy owner. It has been a great ride, so far.
