Yea, if we Roadsters put the top down, an antenna in the window aint gonna work, now is it?

I think they just wanted to keep the "lines clean" as much as they could, so the coupe got a hidden antenna.
I ve often wondered, as I've never owned a coupe and have only test driven them from time to time - does the AM/FM reception in the coupe keep up with that of the Roadster?
