Neat cars. The Type S with the stick was a screamer, I like them a lot.
From what I remember from when these were new, insurance on the CSX was actually cheaper than comparable Civics simply because the CSX wasn't called "Civic". There were a ton of these around the U of T student parking lots when I was there.
Aside from oil consumption, the only issue I've seen on CSXs is the clear coat peel on the hood, roof and trunk. I think that may have been limited to '06-08 cars.
