Well, the Sentra is not a bad car. But the Altis is a better vehicle. And this is reflected by their retail prices.

If you just need a no-frills car with a 700,000 thousand budget, the Sentra might be for you.

If you have the dough, the 200,000 difference may not matter to you, then get the Altis. Otherwise get the Sentra and spend the money on something else.

By the way, if you are paying cash...it is more practical to settle for a brand new car.
