A small town car dealership near where I grew up, in the late 80s, had a Buick Grand National sitting on their lot. This was an absolute bad ass car, and it was amazing that one was sitting on this lot.
Well, being a small town car lot in the 80s, they were more than just a bit lax with security. Therefore, when one of my buddies went and looked at it after dark one Saturday night, he found it unlocked with the keys in the glove box.
He took it about 2 miles down the road and it ran out of gas.
Caused quite an uproar. The cops and the car dealer really wanted to know who took that car. Never found out.
