Poly Engine what was good/bad about it and why is the LA better?

Yes it was.

In the rock & roll era of the late 50s, early 60s we had an Aussie rock legend, Johnny O'Keefe. He had a 59 Belvedere & had a high speed head on crash with a truck. Everybody in the Bel survived, but O'Keefe had facial scars for life from the accident. They made a TV series of his life, & used Colin's 59 Bel for the filming.
