Is this what i've seen in the honda catalogs? Some of the accords have this bump or "wart" on the roof that i think is the XM radio antenna. Am i right about this? I was about to buy an EX with leather and i find that with leather you get XM, which i would NEVER consider subscribing to. So now i end up with this ugly thing on the roof that i don't even need. This may seem trivial to some, but it really bothers me. I've been contemplating going with an EX without leather to save a good chunk of cash, and this may be the deciding factor !
