For Me
Auto-Dimming Mirrors (at least the rear-view) is a MUST
I can live without Power-Folding but it is nice with such large mirrors
The Light Package is cool, but not really worth the 1800

I would say, realistically no, but I always lease so it adds little to the payment so I always say go for it

I didn't have a dimming mirror on my 3.0i and couldn't stand it and quickly had one installed with the compass, the 'Reg has The Dim and Compass again and I love it

The Lumber support was useless to me (The Reg as the 4-way too and I have yet to use it)

Back in '05 the PP added alot more important content for me (Wood Interior, Leather etc)

I would say, leave it off, the 4.8i is a fine vehicle without it but I would add the auto-dim mirror in from the stealership (Mine was 300 something installed)
