Cost of car...! No idea..... i dun work for nissan...? 
3. 5% down payment of the retail price of the Car.
If you bought it at $51K of 5% = $2.5k down of the cost of
Car.
You loan the balance 95% = $51-$2.5K = $48.5k of your car price
which includes COE !
$48.5k loan x ( Interest 3. sometime % over 7 or 10 years) is your
total loan amount divide by 120 months or 84 months. = per monthly
installment !
4. On top of the above, when you drive off is call the on road
fees, includes Insurance + 1st installment = $2k + -
Dun stress yourself, there are more than just one models of the old

6 models and etc...! In Japan there are Bk12(1.4L), AK12 ( 1.2L ),
SR12... and K12.
