How can finance charges be less over a longer term if the interest rates are the same? That's the stupidest thing I've ever heard.
You pay LESS in interest over a shorter term than you do over a longer term.
Just a quick NPV assumption of $20,000 borrowed at 3% shows you pay $938 in interest over 36 months and $1,562 over 60 months.
Seriously. Wtf?
