wow, so much has changed na pala, so for example, I can't just go to the auto supply and say headlight ng 2020 vios? But all headlights of 2020 Vios are the same naman So the shops are just doing that to eliminate errors pero technically pwede naman na walang chassis number?

Last time ko kasi nagpagawa ng car outside the casa was in the late 2000s pa and I never had to provide chassis number when buying parts.
