hey gotabyte...

i myself got a 2003 X5 and i'm the second owner. when i got the X5 it still had 22,000 miles on it so it still has the original warranty but most people here in LA do drive alot so I got the extended warranty as well.

that's just to give you peace of mind just in case of an unexpected problem arising and you don't have to cough up thousands of dollars to get the car fixed, if you know what i mean.

good luck!
