A friend of mine introduced someone to steal a car. Is he the principal offender? If you are the principal offender, how many years will you be sentenced?

No, it's an instigator. There are several situations: 1. How old is the man he instigated? Does it exceed 18? Whoever instigates a person under the age of 18 to commit a crime shall be given a heavier punishment. If he is full, he will be punished according to his role in the joint crime (generally).

Did that man steal it? Did you steal it? If the instigated person has not committed the instigated crime, the instigator may be given a lighter or mitigated punishment. The so-called "the instigated person did not commit the instigated crime" includes two situations: first, the instigated person did not make the instigated person commit the crime intentionally and commit the crime, and the instigated person did not commit the instigated crime or other crimes, and its instigation did not cause actual harmful results. Second, the instigated person committed other crimes instead of the instigated person. In either case, it is an abetting crime and should bear criminal responsibility. However, because the instigated person did not commit the instigated crime, the instigator's instigation has not yet caused actual harmful results, or although it has caused harmful results, it has no causal relationship with its instigation, and the instigator can be given a lighter or mitigated punishment.

Stealing a car belongs to theft, and the amount of theft is huge. Be sentenced to fixed-term imprisonment of not less than three years but not more than ten years, and be sentenced to fixed-term imprisonment of not less than ten years. If it is extremely huge, it may be life or even death.
