Help!! Should I buy or not?

[Bimmerbabe]

I am looking to buy a pre owned 2004 BMW X5 4.4i with 120,000 miles on it for a little under $13k from a local car lot. Despite all the wealth of knowledge online, one may never know the true meaning behind owning a pre owned vehicle such as this unless speaking with someone (or a group of people) that know a thing or two about this particular vehicle, or having owned one themselves.

I've read a lot of negative and positive things online, of course, the negative outweighing the postive but if there are so many problems with this car, why are there so many owners out there??? Should I ask for a 'peace of mind' warranty when I do sign on the dotted line?

Any insight or advice on purchasing this particular vehicle would be greatly appreciated! Thank you in advance
