"OEM" upgrades to earlier 986 models?

As stated previously, helping my dad with his newly-acquired 2001 Boxster is my first foray into Porsche restoration/modification, so I keep trying to apply my non-Porsche experiences to the endeavor with mixed results.

What I have done or helped others do in the past has often involved installing OEM parts from later model years to the older car to refresh and update the car. This includes things like putting 2002 model Infiniti G20 Sport headlamps onto a 1999 car that didn't have the option or swapping in two-tone leather seats where the earlier model didn't have that as an option.

I saw similar practices used all the time when I used to watch the BBC show "Wheeler Dealers."

So I am curious. The 986 Boxster ran from 1996 to 2004, with my dad's '01 falling squarely in the middle. Are there any factory/dealer options that would be desirable and would bolt onto one of the older cars?
