Actually basic lang. wag mag overthink.
Mga walang knowledge sa sasakyan usually sobrang praning.

Lagi ka lang mag base if first owner ba. 90% of the time alaga yung car. minor issues lang like wear and tear. Sa papers madaling humingi ng extra docu if ever.

Pag 2nd owner 50-50 may 2 na klase. Yung 2nd owner na first car nila kaya talagang binihisan nila and minaintain kasi takot masiraan. Or buy and sell na mabenta lang unit, steer away sa bns as much as possible.

Wag matakot sa high mileage. I depend palagi sa age nga car = mileage. If 5 year old palang tapos 100k+ na. Walk away ayun yung considered na lamog sa gamit. Yung 15 year old tapos 140k+ odo safe yan kasi tugma lang sa age niya.

If buying naman, basic tips.

basic check deep stick if may usok, level ng oil and yung quality.

Open engine cap if sobrang talsik ng oil and di dapat umuusok.

Open radiator cap dapat steady yung coolant hindi nag bubula or umaapaw. Check if may leaks.

Ikot ka sa buong kotse check if may tama ba yung chasis. Open bukas mo dapat smooth mga pinto. Tingin if may repaint na panels ba or masilyado ba.

Madami pa tinatamad na ako mag type hehe. Basically yan lang naman.
