1st) reliability and road worthiness
Corolla XL, Nissan LEC
2nd) economy gas-wize
Pride CD-5, LX, Charade
3rd) parts availability
Lancer Singkit, Corolla XL
4th) comfort (yes i put it last since this is an alternate car)
Corolla XL, Nissan LEC

by the way it goes, its the Corolla XL...

but i thoroughly agree with niky's post. don't settle for the brand, but with the condition of the car.
and yes.... charade's spare parts are really hard to find. so scratch it off the list.

and also, beware of the Sentra's Boxtype body. very much prone to rust.
