Is it worth it? I already thought that the regular P85 with 21" rims were kinda firm so I can imagine how this would. But probably better handling/steering? I am looking at 2014 as the 2013 don't have the electric power folding mirrors. I don't think its worth the $3000 labor/materials to retrofit it. So waiting patiently for a 2014 to pop up. are there anything else in the 2014 worth nothing that the 2013 models did not have?
