If the New Mexico owner signed the title and didn't date it, you should be able to sign and date it and the OK DMV wont even know it was in TX. If he dated the title - you will have to pay the back tax on it. I had a signed and dated TX title for my truck, dated like 8 months before I bought the truck. But I was able to get around it by putting it into my in-laws car dealership name and then reassigning it to myself once the title came back. Ended up costing like $48 instead of $250. Good luck and I agree with others, if it ends up getting too deep, walk away!
