HELP PLEASE!! I am looking to buy....

[Roxx]

a 2002 4.4 X5, it has 69k miles. I drove it today and it was strong as a bull!! Tried it in manual mode too....very impressive. All components worked pwr windows, air, sunroof, pdc etc. I know these cars had some issues early on, dont know if the kinks were worked out by the 2002 year or not. Can anyone tell what I should be looking for. I have a 740iL so I am not a BMW novice. We currently have a 2002 Lexus RX300 that has been ABSOLUTELY MARVELOUS as regards mechanical issues. I have only replaced the brakes and tires outside of general maintanence. I am not up for buying "trouble" as my E38 although I love it, has given me a plenty!!!
Your candid input/response/suggestions would be very much appreciated. Thanks
