Before we bought our 2010, we came up with some guidelines for a used or CPO purchase:
1.) No older than 3 model years from current (so 2008 or newer)
2.) No more than 30,000 miles (looking for 10,000 miles/yr or less.)
3.) 50,000 miles or more was automatically excluded
4.) 3rd row a must have
5.) No light colored interiors
6.) Most remaining options were "desires" not deal breakers.

So, given that, none of these would fit the bill. #2 and #4 would not even be considered (miles over 50,000.) If we had decided on a vehicle older than 2008, only #3 would be a consideration for me since it lists 3rd row seat (the only non-negotiable item for the wife.) It also seems to be the best optioned of the bunch.

I'm not positive, but haven't the 2007 4.8's been somewhat of a reliability problem?
