That's the ticket!
But it's more than ther name.
All these cars are driven by someone -real or fictitious- named Kowalski (the most popular Polish name in american films as it seems). Except the streetcar maybe, but we can assume that symbolically and given its name, Stanley Kowalski is the conductor of this machine.
Now to complete this:
- which Kowalski drives this Hornet? (locked for you 48 hours). You are allowed only one answer, of course.
- which Kowalski drove a Mustang, where? Open to all. (I couldn't find a clear picture of the actual car's wheelcovers. In any case, it's a 1966)
