How does the IRS put a federal tax lien on your automobile?

If they do, can you sell the car for cash and keep the money? Can you just ignore the lien and keep on driving (insuring and registering) the car? Thanks!

I believe a tax lein means you owe the gov. money. That must be your only asset. You can not sell that automobile and keep the money. You can't even sell it at all. The gov. has a lein on the title. You have to pay what you owe the gov. before you sell the automobile.
You don't want to mess with the IRS.
