I've had my Altima 2.5SL since May 2011.
$28K sticker, paid $21K.
Leasing would have been about $350/month. After 3 years I'd have paid $12,500 and been left with nothing.
I've only put 16K miles on it and it's worth about $13.5K today. So I've used it for 57 months and "paid" $7.5K in that time period, or about $131/month.
