I totaled my car last week so I'm searching for something new(used). On the recommendation of some guys on another car forum I was looking for a CPO X3 when I stumbled on the X5. The diesel is the main thing that piqued my interest. I'm coming from a Jetta Sportwagen TDI, and of course i can't replace it with one of those. My main questions are reliability, drivability, and maintenance. The main reason I was looking at an X3 is because it seems to fit what I am looking for, mid sized SUV with AWD, and mid 20s for fuel economy. The extra towing capacity would be nice. It would allow me to get a travel trailer to pull. I also think the extra room would be nice, I'm 6' tall so rear leg room is usually at a premium behind my seat. The one I'm looking at in particular is a '12 X5 x35d with Premium Package, Premium Sound, Cold Weather Package, and Smart Phone Integration with 29k miles for $42K. I don't plan on paying that much if I buy it, Edmunds True Car Price is about $35K for a CPO.
