I bought a used CPO 4S last month. One owner lease return, $150k sticker (fully optioned) with 10k miles. Paid $87k for it. So the 40% off is accurate. I test drove the base models which were going for 70-80k and agree with those that say they do feel cheap. If you want it to feel premium, you’ll need to pay a lot more (full leather, race-Tex liner, noise insulating glass, rear steering, etc). Range is pretty good though. I’m getting about 250 miles on a full charge with pretty spirited driving.
