I'm a single guy (live by myself) and own a sedan. I could have bought the same year accord, same price, in a coupe version. But I can't figure out why you'd want to. Basically it's the same car- not faster, not cheaper, not better mileage. The only difference is that it's missing two doors. I use the rear doors to load equipment (guitars) and groceries etc. I think it would annoy me and hurt my back to grab everything out from behind the driver's seat.
I guess some people might think the coupe looks more sporty, but I've seen plenty of BMWs with 4 doors that look more sporty than an Accord coupe.
That's the 4,5,and 6G. On the new Accords, the coupes actually do look different and IMO, much better with the coupe rear end. And if I buy a new one, I'll definately go with the coupe unless they restyle the sedan rear.
