Thought someone discovered that 60 months had more of a quicker payback ie early repayment, more churn etc, instead of going full term. Maybe the 3 year peoples are more procrastinators and have general loans bad outlook- hence borrow for as little as possible, but in general dont juggle the loan as as much. Usually when offered a loan - people have a tendency to go for as long as possible and as much as possible - maybe with outlook to refinance two years into it to a cheap rate. It would be interesting to see 3 year to 5 year early repayment stats - but dosnt matter now as harmony has gone.
