1. if this vehicle will see less than 15K/year and its your first SAV.. ..lease ....a general rule is to use other peoples money on items that depreciate. when you run the actual "cost" of ownership over time you cannot beat a lease for reliability and pleasure of operating a fairly new vehicle. Leasing also gets you out without much damage if you decide the vehicle is not for you.
2. If you go over $20K/year you might want to buy..but either way I would go new..better interest rates and keep most of your own money out of the deal. I would grab an inventory 12 35D if you could..best deal out there of all the Lux SAVs....missed mine as I have to have AD..
