Can't say I have been that fast often, but one time, in the Grand Prix I had purchased from my sister, I was challenged to see if I could do 100. This is the first car I had ever owned. It was while driving to Blackfoot for my field placement at the State Hospital there. I traveled with Blair Gardner and Mary Ellen Spackman. Blair challenged me, "Can this thing do a 100?" So we got off the freeway after Pocatello, and found some back roads on which to try out the Grand Prix. It hit 100. However the springs were so loss it didn't do so safely. The car was really bouncing. Scared me enough that I slowed down as quickly as we hit 100.
That car, likely because of the springs, had a bad habit of hitting the differential case on the bottom, which would push the casing into the differential and it would make a terrible noise. I had to get it fixed a few times, once in the garage and once a friend of Weldon's in Tintic.
