I love the sedan. It's only 60lbs heavier than the coupe. But it's $200 more. It also depends on you. If you're more sporty...go with the coupe. My personal opinion...I don't like the coupe's rear (it's like a bubble). I don't like bubble butts on cars...I like my flat as$ LOL. If you like to have the room in the backseat..go with the sedan. You can't go wrong with ANY Si!Check this out:http://autos.yahoo.com/newcars/compa...e=Compare+cars
