What do you mean by "daytime running lights"? Isn't that something that Swedish cars (Volvo/Saab) have since long time? (maybe not in USA, but probably in their home country).

And the Tempo was the first one to have power seats? Well, I find strange that luxury car did not had that before in USA...

The fact that as car is revolutionary has nothing to do with the fact that it solds well. It may help to make the car famous, it may help to sell it, but it is not always the case.
