What was the song by George Jones that had a verse approximately thus:

"She was hotter than a two-dollar pistol,
She was the fastest thing around.
Long and lean, every young man's dream,
She turned every head in town.
She was hot, and fun to handle son,
I'm glad that you dropped in -
She reminds me of the one I loved back then!"

It begins when the young man drives his hot new car into a service station. When the old man begins the song, it seems he is singing about a long ago car he had - an obvious metaphor for something he valued much more, flaming youth long past.
