Hi Eric,
This is what car salesman, Sales Managers and Finance Managers are trained to do; they look for ways to turn you into a "Today Buyer!" They come up with all kinds of creative nonsense to make it seem like it's a great idea to buy now.
They don't want you thinking about it too much, nor do they want you to leave, because they know that once you're gone there's maybe a one in 10 chance that they'll ever see you again. Not to mention the fact that no body earns a commission until the sale is complete - which is the most important thing to them.
You did the right thing by escaping when you did!
You can see how they play on your emotions. They don't want you to think logically. They know that if you do they're not going to get the sale. They'll tell you anything to get you to think "yeah, this makes sense...let's do it!" It's sad that they have to resort to such sleazy tactics, but this is how the car business thrives.
Just imagine all the "high fives" that would have gone on behind closed doors if you had gone for this deal!
All my very best to you...
Tony Iorio
