I'm looking to replace my daily driver, and I notice that BMW 3 series cars always tend to get high marks. Could someone educate me about the 3 series?

What do the model numbers mean (330i, 330xi, etc.)? Are any years more reliable than other years (I seem to recall an article stating that late-90s BMWs are near bulletproof)? What should I look for in a used BMW?

Thanks.
