Hi muli, aka formality.
Me and wifey studied yun night class on basic automotive and driving doon sa public high school next to the UN LRT station - not sure kung pwede to openly name it sa forum kasi.
Basically ang fees lang doon ay around 10 pesos for the ID and yun mga gastusin sa lessons. Unfortunately, yun teacher namin is a drunk and lazy. Hindi lang makaporma sa amin ni wifey as sister-in-law namin ay secretary ng principal. He taught some but not much and sa 6 months na lesson definitely lacking in substance yun natutunan namin. Actually, 5 months lang ako as nabwisit na ako.
Okay naman with TESDA as how I was told by someone who enrolled there before malayo nga lang and medyo mahal.
If I were you ay hanap ka muna ng good car club as tiyak may mga ladies rin naman who are members of such then kayo-kayo mag-usap to learn the basics of car mechanics na in line pa sa make and model na mayroon kayo. This is why mas favor ko old school then upgrade it bit by bit than buy a new one. Mas fun kasi

Yun lang wala akong major dinero for it to make it a reality

Well, working on that angle soon

FYI. Kapag may computer box ang kotse mo ay yan medyo madugo as unlike old school na gumagamit pa ng carburetors ay high-tech rin needed mo na equipment to properly troubleshoot it. Which was why I recommend invest ka na lang muna sa books tapos unti-untiin mo yun equipments and safety gear mo as you look for a nice car club.
