This is a really dumb question. Rates have dropped precipitously since we bought my wife's car last year, so want to get a lower rate. When it was bought, I just did it in my name. Is it possible to refinance it in my wife's name or is that considered a "sell"? And if it's a "sell", would we have to pay sales tax and registration and all that crap again? If so, it's not worth messing with. Just curious.
