standard or metric

heres a stupid question, i drive a 90 lumina and some one told me that the car is metric is it true?

arent us cars standard.?

ok most of u on this forum drive a lumina and u have no idea?? please help

99% of all the nuts and bolts are metric, yes, but the cluster is almost always metric/US.

my lumina was manufactured in Canada, I live in the us, does canada use metric bolts? Every bolt on my car I loosened is metric so far, so, just wondering. I really dont care, to me its easier to remember that the oil plug is 15mm, versus, 9/16.

yup, mine's made in canada as well. And yup, oil plug is 15mm :D
