new engine for 2003...
my impressions from various sources<br> <br> 2.3l sc engine is as reliable as they get b/c it's been around for a while (according to mbtech208) - used in the slk230 also. but it sounds rough (to me at least), not ultra low emissions, easier to tune w/ pulley upgrade.<br> <br> 1.8l engine - cleaner, better fuel efficiency, people say it sounds better - smoother, lighter so power loss isn't as significant. but new, so no engine tuning parts as of yet.
