I'm really really particular about things like this. I don't like when things match too much. If you can look good without matching, to me that's the ultimate way to make a statement. I definitely agree with keeping the V6 unpainted. I think you did a real decent job with the paint. I would have opted for a darker shade of yellow but I understand you were trying to match things. Can't say I'm a fan of the side skirt lines. It's not terrible by any means, but I think its unnecessary. Just giving my honest opinion.
I do like the idea of painting the LOTUS... think I'll go with a dark shade of gold at some point on mine.
