The juvenile was the one driving the stolen car. S/he can be sued.
It is the thief who can be held liable for the theft. The current owner/driver can be sued for the damages to the car.
really? So if the kid believed he had come to possess the car legally he is still liable?
And for the kid to be liable for any damages, plaintiff needs to prove defendant actually caused damages. Maybe the kid got it with worn out tires and broken windshield.
But I disagree with your premise in general. The thief would be liable for damages stemming from his actions of stealing the car in similar fashion that felony murder is charged against the getaway driver of a car where others entered a bank and shot and killed a person within the bank. If not for the car being stolen by the thief the op would not have sustained the damages incurred, regardless of who actually caused the damages therefore thief is liable for all damages incurred by the owner of the car.
