I disagree with your disagreement... too many colors... blue white amber... I'd make it cleaner... so white lights match the white decal and rims...
got the same overall look with a different color and ambers on my car would throw it off...
it's less a period look and more of a current spyder/new model look...
unless you make the porsche font on the decal larger like the older 911 912's
...then again that's just my opinion.
