Worked at GM all thru college. Secretaries that took care of the pool cars were all very nice to me and hooked me up with nice rides whenever I needed to go somewhere. Took a late 80s Firebird Formula 350 on a lonesome Michigan highway. Speedometer went to 150 and kept going all the way past and back to zero. I don’t know how fast it was exactly but the car started to feel very “light”. Glad I got that out of my system without incident!
