Like I said, "probably kept it going way too long".
However, it was a low interest rate loan, so time value of money, and ... yeah, not Ramsey Approved, but in terms of debt... well, I won't say it's "good", maybe, it's the least "offensive".
I kept it going too long because at 2.85%, it made more sense to put any extra cash into my mortgage which was at a higher rate. For part of this time, I also had a car loan- same thing. Never even close to default, so everyone in the mix got what they bargained for.
