Rodeo models that do not connect to a computer for diagnosis

Hi, I am in Panamá Central America. I am planing to purchase a Isuzu Rodeo here in Panamá. these is what I have found so far:

a) Rodeo 98 2WD 4 Cyl 2.2 / 90,128 miles $6,500.00 The outside is impecable.

b) Rodeo 96 2WD 4 Cyl 2.6 / 89,234 miles $4,500.00

c) Rodeo 94 2WD 6 Cyl 2.4 / 114,000 miles $4,500.00

c) Rodeo 94 2WD 4 cyl 2.6 / 139,410 miles $3,500.00

c) Rodeo 95 2WD 4 Cyl 2.6 / 144,888 miles $3,500.00 (condition poor)

I am looking away from 3.3 v6 motor, because of the price of gasoline.

My main concern is to know wich rodeo model, you do not need to connect to a computer. for troubleshoting. I prefer to have a very simple car. because of my budget.

Thank you.

Up to 1995 does not have the computer interface port (pre OBDII). Keep in mind the 4cyl rodeos are no better on gasoline than the 3.2L. I would personally stay away from the 4cyl, especially the 1998-2003 2.2L due to reliability concerns.
