When I was looking for a CPO, the adviser assigned to me was able to get me waaaay better deal cars than what is listed on their website.
I bought new, but when I was taking delivery, I saw a lady picking up a CPO model S for $20K! It looked mint. The DES and I joked that we would have each bought one just to resell for a profit.
If you don't believe me, call Fremont Delivery Center. My DES is Scott Burry, but he wasn't there to deliver the car, it was someone who was his backup. Not sure his name. This was on Monday 8/21/17 11 am.. I saw the CPO with my own eyes, and the delivery guy saying that the lady paid $20K for the car, and I checked it out - and saw that it was in great shape. The delivery guy said that he wish he could have bought it because they are rarely that cheap, and I jokingly said, i'll buy that AND my new S if she backed out.
