Some of us with 300Es also own other MB models...personally, I like to be able to ask (and solve) problems on any model without having to jump around to different forums. Plus, I can also get a good idea of what to expect when looking at a prospective non-300E MB purchase (new or old). Some topics that come up affect many models (i.e. synthetic oils). I say we keep the forum as is. I'll use the search engine if I want to see specific 300E topics.
