as chinyoti mentioned
I agree
but there is no such problem if you are getting low mileage manual sz3
all parts are cross-compatible because Cultus itself has 90%+ imported parts same as Celerio, the rest are locally manufactured now (like from 2020 onwards, windscreen), you can use all cultus parts for celerio
from reviews I have got so far, other than paint quality and exterior panel gaps, there's no such significant difference in both cars, being a blindfolded passenger, you can't tell whether you are in Celerio or cultus
so don't worry if you fail to find low-mileage Celerio
try to find dealership maintained car, and before finalizing, cross verify car mileage from dealership maintenance database, in case odometer is reversed, you can identify that from mileage mentioned in maintenance log
