How to undo car set to online

[SuperNik]

Please excuse me, I'm a bit of a noob.
I've set one of my cars to online and now I can't drive it.
How do I undo this?

Sorry if this seems like a dumb question.

Go to the car in garage, menu, select online and choose off.

Thanks for the help.

I'm gonna go stand in the stupid corner for while.
