But what "shady sales tactics" are we talking about here? What exactly was shady?
The OP got (or will get) exactly the car he ordered, and exactly the price he wanted. And as a
bonus, he has the opportunity to upgrade to something much more than what he was expecting for pennies on the dollar. (And in actuality,
not taking advantage of the upgrade would be screwing yourself).
I just see nothing shady here. If the exact car that the OP ordered dropped in price a week later by several thousand dollars, then we have something to complain about. But that's not what happened. They didn't change his order, they didn't charge him more, they didn't make him wait, and they gave him the opportunity to essentially get the new upgraded vehicle for a very low price. The only issue is that if he had ordered 2 weeks later he would have saved a bit.
Let's put things in perspective. The $500 change fee amounts to a price penalty of less than 1% on his car. That's exactly analogous to purchasing a cheeseburger today at $6.99 only to learn that tomorrow they've dropped the price to $6.92. And for that, we're throwing around the words "shady" and "misled"?
Balderdash.
