Honestly and painfully, there's no such thing as "best buy" at that budget as you'll be guaranteed to spend almost the same amount fixing it to be road-worthy and not leave you stranded with car problems every month.
Im also new here..... I got my corolla for 100k but i still have to work on it every weekends I guess you cant get the best buy for a toyota at that price sorry....
try those small cars like daihatsu, kia pride, daiwoo etc. but always remember to prepare a little more money to spend for some repairs and fine tuning of the vehicle
i think "best buy" toyota for that price will be 1989 corolla XL (in poor condition). you may have to spend about 50k to make it almost trouble free, wala pa yung aesthetics..
so kung toyota talaga gusto mo, ipon muna para makadag dag sa budget. mga 120-130k may makukuha ka ng maayos ayos na early 90s sentra ss, big body corolla (xl) or a GL/GLI na AE92.. and its always best na meron kang budget for repairs otherwise you'd end up with a 2 ton paperweight.
