I am a new guy in the US and my credit history is ~6 months. I've got a 20k 60 months 11% APR loan a couple of weeks ago and bought a new car. Technically I am able to pay it off not in 60 months but in 6 months. My wife's parents gave her 15k as a Christmas gift so we may use this money as a first month pay.
How such fast paying off will influence my credit history and score? Maybe it's better to pay off in 12 months or 36 months for my credit history?
