The next time you read a car advert, it may mention that the chassis is X% stiffer than the previous generation, so it can improve the handling and ride - usually at the same time. This is one reason why the (say) BMW 3-Series rides well and handles well. There are other reasons too, like low unsprung mass, which helps. But anyway, the reason why a stiffer chassis can improve the ride and handling is that as chassis bends and flexes over use, the suspension is less efficient or more compromised. Those small movements do, I'm led to believe, make an appreciable difference. It'll only be subtle, the bodywork will be built to a tolerance, so you probably won't notice it - not to mention that windscreens are structural components. But bits move ever so slightly. At the same time the suspension components are also moving. Of a sort, the chassis is partially acting as the suspension. Of course, over a tight corner, the suspension is better at being suspension than the chassis twist. This is partially the reason why your 9-3 will have a top mounted chassis brace in the engine compartment. The other is that it improves crash robustness. >>> The stupid thing is that a lot of the saloons I see around look like >>> hatchbacks.

I have a sneaky suspicion that the manufacturers originally designed hatchback-shaped saloons to benefit from the improved structural strength (for crash protection and improving the drive) without making the car _look_ as though it was designed to be stronger, if you see what I mean... >>> The fact that people continue to buy these hatch-shaped saloons >>> suggests either that they have some kind of wierd brain disease >> >><shrug> Probably.

People who must have the latest in (whatever) usually have no appreciation for what their discarded item is worth. I love these people.
