Is there a way to get failure stats on used X5s?

I'm considering buying a used one. I need a (smallish) tow vehicle and don't want to pay the ridiculous new prices.

However, based on this thread... maybe I will look for a Japanese equivalent (Toyota?) I am a little worried about maintenance in these over-complicated used "luxury" cars.

Any input from X5 owners that are 80k miles or more? 130k miles? How's your X5 doing? What repairs have you had to do? Are all the accessories working, or have all the little James Bond features begun to break off of the car and fall down between the seats?

Just wondering...
