For an acquaintance, not worth it! For a friend, go for it!
This is another part of the equation. If I had to categorize her on a scale between "acquaintance" and "friend", she'd definitely land much closer to the "acquaintance" line, even before this request came up. I'm just not close enough to anyone IRL that I would even consider engaging in a minor violation of the law (like a parking ticket), much less participate in Grand Theft Auto.
Come to think of it, when I was a JW (over 20 years ago now), one Sister™ invited me to go in Service™ with her. Of course, she didn't own a vehicle, so it was necessary to use mine. We went to one of her Return Visits™, and found that there was no place to park nearby. She thought it was a fine idea to park in a No Parking area, and even though I objected initially and offered to let her out to do her RV herself, she eventually talked me into parking illegally so we could do this Not-At-Home Return Visit™. We weren't gone from the car for more than 5 minutes, but there was a $25 parking ticket on my car when we got back. Her reaction? "Oh, that's too bad. If I weren't Pioneering™ and could afford it, I'd pay for it, but I really can't help you. Besides the ticket is in your name, not mine." Then I asked her why, if she couldn't afford a ticket, would she put someone else in a position where they'd have to pay for one? I drove her home, dropped her off without a word and went to the police station and paid the ticket. And I never went in Service™ with her again. She never even offered to share the cost of my gas either. From that point on, I listen to my "User/Loser" Radar every time - it's never failed me.
