My older brother had one of those. He couldn't drive it without trying to see how fast it would go.

As I remember, it had an automatic suspension adjustment that provided automatic levelling. My brother had to mess with that and make the car do weird things when it was standing still. He was a terror on the highway and I don't know how he kept from being locked up. He was as likely to pass on the right as on the left on a 2-lane highway. I absolutely hated having to ride with him. I was embarrassed and afraid. Perhaps that's why I don't care for that Packard. I think his lasted three months before he blew it up.

It was far to good of a car for him. To this day, I don't know what he thought he had to prove.:confused3:
EDIT: My brother's longest lasting car was a 1951 buick staight 8 with a Dynaflow transmission. As hard as he tried, he could not blow up that car and actually ended up selling it.
