i think this is second time this thread has been derailed into judging people who take long finance terms
obviously it's not the smartest thing to do financially speaking, but there is an obvious benefit to financing over a longer term even with interest - LOWER PAYMENTS. and thus more comfortable monthly cashflow.
Is it better to be tight on cash every month and have your car paid off a few years earlier or have a little extra cash every month that you can save/invest? Personally i prefer the latter as long as the interest rate is reasonable (4% or less) and you are making good use of the extra cashflow instead of pissing it away
