Nope, never was promoted as $25k but instead as $35k car, not $25k. Also, you can apparently still buy the $35k car (same as the $38k Standard Range Plus but with some of the range locked out at autopilot features reduced--but you still can get that 200 mile range Model 3 if you really want it), but you have to call them about it. Only 8% less money, though, for like 20% less range and fewer features so probably isn't worth it.
