If you buy a car or truck in OK, you have 30 days to get it transferred over, or you pay a one-dollar-per-day penalty after that, up to $200 on top of the normal transfer fee, title fee, and 3.5% excise tax. Also, if you buy in OK and take the vehicle out-of-state, you'd better pay attention to the 30 days, too...why? Because when you go to title the car in your state, Oklahoma will refuse to release the OK title to your state until the OK Tax Commission is happy. What they'll do is tell the buyer to get the OK seller acquire a duplicate title, then re-sign and notarize it to the out-of-state buyer.
Oh, and if you bring a car INTO OK and try that "sitting on the title" thing and go to get an OK title and tag after 30 days, that penalty also applies to titles from out-of-state, too!
I know this has little to do with the Nevada car in question, but some of you really live in lax states, if you can sit on a title like some of you claim to do.
I refuse to buy an untitled vehicle, unless it can be verified without a doubt that the car was last registered in a state that did not require a title, AND come with the tag and/or registration, along with a notarized bill of sale.
