I'm buying a XC. I am looking at 2 cars. One's a 2004 and one is 2006. I like them both but the 2006 is a stretch financially (want to pay cash). I have heard from a few people to stay away from the 2004 because of a few issues. Is this true? What issues??? They are both one-owner, excellent condition and similar mileages (around 115k). Please - you input will be extremely helpful in my decision! Thanks
