Plenty of modern cars, even fairly modest sedans, are predictable and stable up to around a hundred. Go beyond that and the number of predictable and stable cars falls off pretty rapidly. Not very many are drivable at all at 150 even if they could reach that speed. 200 is impressive for a largely factory spec car from any manufacturer.
My ‘92 Saturn SL2 would do 115-120 and felt great at that. Oddly enough, that was the only car I ever got speeding tickets in, and in California to boot. I believe that was a combination of it’s extremely good handling at speed, it’s “oddity” factor since they weren’t all over the roads in the first few years and the fact that they didn’t start using radar on CA interstate highways until the late 90’s or early 2000’s.
In Virginia, I had my 1970 1/2 RS Camaro up to a rats ass under 150 once, for a while, and it was pretty tight too. Most notable was that power steering was a waste up in the 100’s. I had new tires, brakes, air shocks and station wagon coils and Berlinetta leaves in it, plus a shift kit, headers and a bit of cam under the hood (though still the 2 jet on top). My Z-28 pack had rusted out on it and it sounded like a low flying aircraft.
I have a picture of me standing next to it (in my 1982 WHO concert T-shirt) in our office kitchen at work captioned “NEVER sell that which will be extremely difficult to re-aquire in the future”...
