Note that both ELC and CCR are options, and not every Bonneville has them. My 97SE has neither, but maybe it'* an SSEi thing or something. (Someone please clear this up.) So you might not have them to begin with. And like others have said, even people who have them generally replace them with non-ELC, non-CCR struts, and get a good ride anyway. I've driven other cars that have ELC, and I must admit that'* a pretty cool feature. Had my car come with it, I'd want to keep it. Either way, as long as you go with a high quality replacement, you'll be fine. Stay away from cheapies. The stock ones are really quite good.
