Auto Vehicle Sales Tax

[bmac82]

I purchased a car from a private party. I went to the DMV and tried to register the car but they said I would need proof that the previous owner paid sales tax on it. He never registered the car and I can not get a hold of him. What do I do??

What is your state?
How much is the car worth?
Will they let you pay the taxes?
Do you have a bill of sale?
Where was the car last titled?
