I don't have an SVX yet, but I have had rattles a squeeks in numerous cars.
The silicon spray does help rattle, it only helps plastic against plastic squeeks.

The silicon spray removes the friction between plastic parts, and its not corosive of dangerous. and its easy.

But I agree that taking the car apart is the best way to resolve the rattles.

But can be frustrating if you dis-assemble and re-assemble and the rattles are still there.
My experiences have been rattles in doors, dashboards, and sunroofs, in other than SVX's.

So take my advise with a grain of salt.

Squeeks can be fixed with silicon spray without taking anything apart...if your lucky. It a quick fix, and usually last a while.
