Given your choices and priorities, here's my opinion:
1st) reliability and road worthiness
1989-1991 Toyota Corolla XL 1.3L, all manual
2nd) economy gas-wize
1991-1995 Kia Pride CD-5 or LX sedan 1.1L, all manual
1993-1995 Daihatsu Charade 2dr/4dr 1.0L, all manual
- former Charade owner here, hands down talaga ako sa tipid
3rd) parts availability
1988-1991 Mitsu Lancer singkit EL/GL 1.3L, all manual
1993-1995 Mazda 323 LX 1.3L, all manual
1983-1985 Mitsu Lancer Boxtype SL 1.4L , all manual (although quite older)
4th) comfort (yes i put it last since this is an alternate car)
1988-1991 Nissan Boxtype 1.3L/1.5L/1.6L, all manual to all-power
1992-1993 Nissan B14 1.3L LEC, all manual
1988-1990 Mitsu Galant 6Gen SS carb engine 1.8L/2.0L, all power
IMO!
