That simply is not so.
70k is actually slightly
lower than the average transaction price of a new GMC Sierra (which is $71,718 and whose annual sales are RIGHT about where Tesla said their annual CT sales targets were), and only slightly higher than the ATP of an ICE F-150 ($66,787).
Assuming the $7500 rebate applies to CT then a 70k CT would be
less than what most truck buyers can afford or want to afford.
Since even if you HAD a case for false advertising at the reveal (which if you go back and look at what was said, and how it was said, you don't) your max damages would be a few years of interest on your $100 deposit. GL with all that.
