1996 - 2002 Surf will be expensive in this budget. Pajero can fit in. But it can be quite a hectic search to buy a good condition vehicle while staying within the budget.
This generation Pajero is comfortable, good off roader. Different versions are available with nice options like ABS, heated seats, sun roof etc. Well kept vehicles are reliable.
Maintenance depends upon the garage you select. A mix of new and used parts can be found. New suspension items available from market and body parts to be sourced from scrapyard.
If buying it, please try to find 2.8 Diesel.
