There are several ways that you can tell between an EX or LX trim on a Honda Civic. Meanwhile, the LX is the base model Civic that you'd start off with. Therefore, all that extra luxury does make the EX heavier than the LX. And, you'll note how the LX wheels are steel, while the EX comes with a set of aluminium wheels. The EX also has a moon roof, as well as a larger engine, and more ground clearance than the LX. You could also find more tech in the EX than in the LX. A Civic with the EX trim would come with 6 speakers instead of 4. And, there are other tinier differences that you might be able to notice - mainly since the EX is a premium trim.
