car: 93 civic si

I've noticed more and more lately that my car seems to be vibrating a lot on startups and while idling during this period. The car has about 105k on the chassis. Is this just aging of the chassis and the bushings of the engine mounts and everything else? I can see my mirrior shaking more and my steering wheel virbrate a little more.

Is this repairable by replacing bushings and such? or is it just something to live with in an aging car?
