How fast have you gone in a gas sipper?

So, we are on a road trip in west Texas going 85mph on I-10 in my wife's Armada. Nissan versa hatchback with a smashed front bumper passes us like we are standing still. And the wind is really whipping out here, blowing us around and we are loaded for bear, three kids and camping gear.
How fast have y'all gone in one of these little cars. Not the Nissan Versa specifically, just any little car like that. Do they get squirrely with body damage at that speed? All my vehicles have V 8's. My wife and I are driving along wondering and I said, The guys and girls on FABO know all! Figured it would make for an interesting conversation anyways.
