My Saturn still has many of its original parts, including the engine, which has never been touched!

You and me both. If it aint broke, don't fix it!

I wish I could be like you guys sometimes. In my 96' SC1 (224,000) all the mechanical parts are almost original, but my 94' SL2 is not original at all. I rebuilt the engine for racing. It still has the same engine block, but that's just about it. Anything I saw in the engine that looked replaceable was replaced.
