Does your Mirage start to shake at high speeds, like the 90 mph mark?

Hi Mirage Forum members, I noticed my Mirage starts to almost shake a bit at short duration high speeds (85+ mph) on the freeway. Is this normal?

I'm not worried about it, pretty much every other cheap econo box I have ever driven does the same thing.

My Mirage is nearly silent at idle, so the motor is fine, and my Mirage drives straight as an arrow, no alignment or tire problems, they're pretty new still.

Not worried just an observation, the Mirage is not really meant for high speeds.
