He’s got me; best I ever did was 115 in my 1972 Mustang Mach I on I 465 in the wee hours of the morning. It had more to give but the Ford steering was so bad, I was starting to drift between lanes. That was enough for me.

I have seen that happen to a Mustang. I had a guy in a 70's era Mustang II trying to keep up with my Saab Turbo in Oklahoma. At 105, he had a hard time tracking his lane. I pushed it to 140 and he quickly disappeared from view.

Even medium-priced Euro cars are indeed designed to do 100mph and remain stable. I believe a lot of Americanized Euro cars (like the smaller Buicks that are actually Opel designs) are altered for more sedate American highways.
