they cannibalise other cars.
complete cars are shipped as vehicles, scrapped cars are shipped as scrap which are used for spare parts (shershah etc).
so the salesman tells - sare parts miltay hain 5 minute main, ghar beth ke, 100 rupay ka andarr.
customer is super delighted to be driving pokemon car with ultra super cheap parts supply, When he goes to buy any parts - he loses his shirt.
btw - it is some local car - it has the CNG sticker on it.
