I found a source for a bolt-on hitch for my wife's Prius, though Toyota wasn't going to void the warranty for having it attached. I saved the tie-down hardware that was bolted where the hitch attached. If anybody cared, I'd have swapped the hitch back out before taking it in for warranty service. You could probably find something like that for your Accord (or ask your google-fu master friends/family to find it for you!).
