Have you checked out Groar's Uglyback? It's a roof extension short enough to not interfere with normal trunk operation. I say: "Try a full extension that hinges up."

What matters is where you're going, not how fast.

Piwoslaw: Thanks for the link to the Uglyback. I am considering doing something similar (actually exactly the same) to my car, but it won't stand out so much since I bought white duct tape and have white coroplast for the job AND my car is white!
