So many customs miss the mark IMO
With most of these older cars like the P1800, I think they are so hard to improve upon the original design.

Some custom details work better than others, but creating an overall package that improves on the original is not easy.
Until your build, I really thought the best rendition was one that stayed pretty true to the original design (none of which have flares--but notice the side view mirrors):

But, Im really diggin your design and think it may rise to the top. It would be a remarkable accomplishment to make a custom that compares favorably to the original design.
