im planning to buy a pickup at the mentioned amount. i am considering a mazda b2500 and any isuzu pickup with the same price range.

my questions are:
1) what year was the latest release of b2500?
2) what isuzu pickup ang kaprice range ng b2500?
3) please compare the cars by performance, ride and consumption.
4) what should i look out pag bibilhin ko na? i guess common issues ng mga sasakyang ito.

if meron pa po kayong ibang suggestions, feel free po. maraming salamat!
