I would also pass, and save the grand or however much it'll cost.
Like Jake said above, it's too hot, and I rarely use a sunroof. It's also one more thing to break, leak, etc. Plus all that extra weight up top will really kill my lap times.
It is cool though.
Yeah don't remind me, we have crumbling infrastructure (bridges) where I live, big rocks and chunks of concrete sometimes falling on cars. Even with the fabric cover closed, the risk level where I live is too high.
