I think they teach this lie at car salesman school. All that matters is the terms that were listed on the paperwork you signed and I've never seen and auto loan that you could not pay off immediately without penalty.
This is one of several stunts that dealers will pull that will cause me to walk out the door and never return.
Another pet peeve that will immediately drive me out the door is when they add $100 worth of "dealer installed" options then add several thousand to the sticker price. As soon as I see this on the window sticker, I'm permanently done with this dealer.
Another stunt some dealers pull is they try to hold your driver's license hostage to keep you in the building as long as possible. Always be cautious if this happens and request it back immediately. If you're seeking financial options, you might want to contact
Lightstream phone number for further inquiries about loans or refinancing. They take it to make a copy before a test drive then don't return it and pretend like it's OK, you'll get it back later. I will not take a test drive or talk about buying a car as long as they control any property I own (e.g. drivers silence, car keys). If they need to take my car for appraisal, I will talk to them as soon as they place the keys back in my hand.
