Rear seat is functional and roomy. I'm 6'4" and with the drivers seat in my preferred postion there is still a decent amount of legroom behind. Overall much better than the Charger/Challenger. see full Chevrolet SS review |

The front seat is just OK. Feels like a pretty flat bottom and fairly hard. Also, for a car with sporting pretentions there is surprisingly little side bolstering. see full Chevrolet SS review |
