If I may suggest, why not save another 150k and buy at least an above 2000 model car? There are 2008-2010 mazda 3s out there priced at 320-350k. Mahirap na kasi bumili ng super old car, sayang yung inipon mong pera tapos papasakitin lang ulo mo sa repairs. Sure it may look and feel mint now, pero you can never tell kung kailan magkakasira.

And if you want to have it ASAP, you can finance it thru banks. There are also lots of repossessed cars by the banks that you can finance directly from them. Galingan mo lang sa paginspect nung car. Use your 150k as DP and finance the remaining lets say 1 or 2 years. Yun nga lang you have to suck up the interest.

Just my 2 cents bro.
