My girlfriend recently purchased a new Honda from a dealership in Texas. She applied for financing through Honda and Capital One. The Honda finance manager told her both interest rate offers were the same, and we decided to finance through Honda. After the sale was finalized, we realized we never personally saw the offer from Capital One, so my girlfriend called them. Capital One told her what their offer was which was significantly lower than what the Honda finance manager told us.
The Honda finance manager lying to us about other financing offers was clearly unethical, but did it violate any laws? If it matters, the difference in the interest rate will cost her about $687 over the life of the loan assuming no late payments, additional principal-only payments, etc.
