Ironically enough, it was probably my dear-departed (totalled into the side of a s*itbox Bronco) Audi 100 (A6); it was not particularly fast off the line, but it went up to 130 mph easily, and had more left. "long Legs," as they say.
I had a 1969 Chevy Caprice with the high-output 350 (300 hp), it was smooth and silent, and I got *it* up to 125mph quite easily, but lacked the guts (I lacked the guts, not he car!) to go faster. That was on bias-ply tires (that is, they were not radials); and with the soft-sprung suspension, at that speed, even on a nice open stretch of I-35, it was a white-knuckle experience. I am probably lucky that it did not kill me then and there, but God protected this fool that day.
If my current Caddy deVille did not have the electronic rev limiter, I imagine it would do 150 mph or better; it gets to 112 (the electronic limit) without the remotest difficulty, an dthe DTS (with only a few more HP) gets to its limit of 135 quite easily as well. I'm going to see whether there is a chip hack available to get 'round that 112 limit. Like I need it.
No, those are cars I *owned*; fastest driven:
...and look at the Series 1.
...three miles from BRONS, clear for the ILS one five approach...
