After more than 10 years of driving my X5,3.0 it finally broke down and left me stranded in GA on 95. I was able to switch out a new battery and go another 225 miles closer to home in FL even though the alternator was diagnosed as toast. I am wondering why the alternator didn't give any signs. It just broke.
Granted this is an 01 with 218 K miles. SO, the question is , how much to spend on a new , not remanufactured alternator. What brand do you all reccomend ? I don't know the amps yet, 90 or 120. Or the brand Valeo or Bosch, but I see some aftermarket stuff and I am wondering if they are worth it. Be nice to get another 30-40 K out of this X5 before moving on.

Thanks.
