Hi. Need your views desparately before Sunday.

I plan to purchase a Nissan Patrol '91 model. Asking price 200k. Owner says no mechanical problem and road worthy and fuel efficient.

This is my first time to own a 4x4. Any inputs on spare parts, common mechanical problem and other possible sakit ng ulo will be greatly appreciated. I have limited budget so I could also need some tips on how to maximize my money. thanks
