Okay I just picked up the car (drove it with a shakey leg from excitement/nerves) and also spoke with the estate lawyer. I just have to pay the inheritance tax and take some documents that he will send to me to DMV. It essentially becomes a "gift" at that point as far as sales taxes go.
You have no idea how NJ is, once I bought a car and paid taxes on what I paid for it. After 3 months, they sent me a letter stating that it was worth $3K above what I paid for it. What a hassle that became!
Thanks for your help and suggestions (but not the "failing" grade) gongtowjai, I appreciate it!
