PLEASE HELP TO DECIDE!!!

Planning to aquire a 2002-UP model ng Pick-Up,

Preferably a 4x4 but ok din na 4 x 2.
Budget is less than 500K
Diesel but efficient and good engine
Fuel efficient in its class
Low Maintenance Cost.
Medyo sporty and yet pang workhorse..

Frontier / Ranger, trekker/ Strada / Isuzu / Toyota

Thanks....
