Salvage titles

If he is legit, he will be willing to transfer it into his name first.

The reason most guys do not want to put the cars title in their name/state is because they do not want to pay the sales tax on the car.
They plan to sell the car or don't want to license and drive it.

I have bought and sold cars like this in the past.
Of course as mentioned there can be some issues with this.
