bosing...are you sure you want to get 2nd hand seats, or for that matter, anything fabric?

di mo kasi alam kung anong natapon diyan - food, drink, vomit, blood, fecal matter - you get the picture. lalo na kung family vehicle yung pinanggalingan niyan.

anyway, if you still want to do it i would recommend at least a reupholster. you can clean the seats with seat shampoo and stain remover (available at any auto supply shop), but i still wouldn't trust them.
