We just bought a '99 Civic Coupe EX. I wanted to ask what's different
about the year's '99-00 as I see these two years offset from '96-98. But
they look essentially the same, except for different colored tail lights
and headlamps.

Can anyone tell me if there are structural/part/engine/anything
different about 99-00 model years vs. 96-98? I'd like to know for
aftermarket purposes. Thank you.
