Except a 747 is not a Ford.If I walk into a Ford dealer and they tell me I can have 30% off anything, I don't think I can really expect them to sell me a 747.
If you walk into a ford dealer, they tell you you can have 30% off anything, then you expect anything, but not half the range missing.
I'd take an F350 with 30% off. - Sorry, we don't have that in stock.
How about an F250? - Sorry, out of stock too. They next town has them, but at full price.
I'll take a Ford Ranger then! - Can't have that either, sorry, not at this place. Go next town. Why not have a Ford Fiesta?
