Interesting to see the yellowing in the enige bay. It isn't bad thing thing in my belief.
You can't recreate patina.
Yes exactly...it seems Polaris paint does this over time if not touched (especially in the engine bay)...i.e. a good thing, yes.
May not look good aesthetically, to those that don't know this.
The seller Wob is a heavy hitter on BaT if you look at his profile and all listings bought/sold seem to be quality presentations.

No affiliation whatsoever...anyhow, nice to see an E9 in this shape, honestly presented it seems. I hope it hits reserve as it seems to me it has a long way to go.
