You buying new car? Check with the car distributor if penalty
charges imposed or not for one shot payment. Due to the fact that
showrooms pocket commission for encourging customers to take up in
house finance, if you pay one shot you will be surcharged some 1~4k
on top of the selling price. Do consider this point. If you buying
2nd hand, by all means yes go ahead if you got enough left in your
pocket for (not rainy but) Tsunami days.
