"I've got a slick"

The French guy needs more help !
I'm unable to find exactly what slick means. It's about a car in this phrase.
Thanks

I'm not sure. Tires get slick or bald when the tread wears off. Or could it be an oil slick under the car?

Well, let me give you a little more of the text:

"You want to drive or you want me to? I've got a slick. What have you got?"
- "I still have a plain jane"

"Plain jane" I found it, it's something ordinary, not fancy or glamorous. Farther in the text, the "plain jane" is described as "a beat-up maroon LTD, at least five years old, and about as impressive-looking as a Pinto".
So slick might be a word to describe the overall state of car, perhaps as you would say "I got a lemon"?

Hope this will help. Thanks again.
