I hear you. I was looking at older ones and found a nice 2005 4.8is with 48K miles with no warranty as it was at Carmax. Looked into the company they use for extended warranty and never heard good things. I am in a similar when looking. Either buy a CPO car that has under 50K miles and pay to extend the maintenance to 6 yrs and 100K and let the CPO take care of any covered repairs. Only issue is for a 2007 or 2008 X5 4.8 I am looking at close to $40K which is more than I want to pay.

Seems like the BMW's start to become affordable once they hit that 4 yrs and 50K miles. Most people are unwilling to buy ones of these and be making car payments and on top of that have to dish out big money for maintenance and repairs.
