I am willing to prepare for you; I asked him to repair my car. Lu here refers to the person who repairs cars.

You can say:

In my office. It means that I entrust my car to my male ticket for repair.

If necessary, for example, if you happen to be a man and you don't want others to misunderstand your friendship, you want to use pronouns to refer to your male ticket. You have to say:

I'm happy to serve you.

If it is necessary, for example, if you don't want others to know that you have a car and come to make friends with you, and you want to refer to your car with pronouns, you should say:

I want to go with you.

For example, if it is necessary and you don't want others to know what you really want to say, you should say:

I'm ready.
