If you're looking for cargo room, the Fiesta is by default not the car for you. If you're buying the Fiesta ST it's because of the factory handling upgrades and performance. The Accord just isn't even the same. For that matter, you can get a regular Focus for less than a Fiesta ST or a Fusion for about the same price. Both have more cargo room as well, but they aren't performance models either. If you want to go test out a Fiesta, find one without a moonroof because it lowers the headliner. If you want to check the fit and you can't find an ST just try out a regular Fiesta, it's the same inside.
