If you like entering it in Concours then you could fret about it, otherwise its no big deal.

If it was me and its still bothersom then obscure it with a Boxster sticker.

If you need to change your focus and perspective to get past it then read the IMS Failure threads and all the wonderful modes of failure for your engine.

Also watch some of the Boxster track racing videos in the Race forum. I did that during a break today and you should have seen how I drove the Boxster on my way home.
Puts your head into a whole different space where paint colors and rainbows give way to growling engines and adrenaline.
