I just purchased a 2015 CPO Leather AWD with 42,000 miles in December. I paid just under 25 before taxes. I feel I got a decent deal and am very happy with it. The NAV is OK, you cannot enter a new destination while moving over 5 MPH, even as a passenger. It works, and if you have Onstar you get traffic alerts. I have the DVD package so I can play a DVD and see it in the front while parked, nice feature. You can always add a trailer hitch if you need to haul something light, if you need a full blown package the dealer or an after market installer can install it.
Hopefully they did get all the bugs out of this vehicle, I had a 2008 Outlook , I put some bucks into that, transmission, water pump, steering pump, steering rack, struts, but I did get 212k on her and sold it, the new owner is happy with it. I do have confidence in this product and hope to get another 200k on it.
