in '08 the storage pack (which includes compartments under each front seat, a mesh pocket in passenger footwell, mesh pockets on the seat backs, and the rear cargo net) was included as part of the enhanced interior package but for whatever reason it was ommited from the s-line package. AFAIK there was no way to add the storage pack as a separate option, so those features are not present on s-line cars. I'm not sure if this is still the case for '09 cars.
