2011 5.0 Convertible questions

I am close to buying a 2011 5.0 convertible (manual), and have a few questions for the group:

1. What is the benefit of cloth or vinyl for the convertible top? I assume cloth is better, but am unsure. I live in Florida, so the car will never be in snow, but will get beat down by the sun.

1. Are there any after-market mods considered very important that I should consider? Way back in the past people used to talk about subframe connectors and such, so I was curious.

Thanks!
